    I have 76 panels for 26.22kW DC at the panels and a peak 23kW back to the grid. Sunny boy 3x 6.0 and 1x 5.0. Since we weren't in the house long a large basis of estimate was how the previous owners used power. Big difference between an older couple with grown kids and a young family with...
  • Post in thread: psa: Chargeverter is LOUD

    I took some time to go through and look at the various Meanwell supply's that seem to work. It is really interesting because de-rating's can hurt you quite significantly especially at the 115V line voltage. These are all the fanless supplies by the way. What's interesting is you can get more...
  • Post in thread: NYSERDA

    I have thought of possibly doing an opposite east west facing I just don't know if it pays. As it is I have 76 panels that are ground mounted facing due south. In order to maximize my solar production overall my inverters have extra panels installed on them so they seem to peak out longer but I...
  • Post in thread: NYSERDA

    I generate about 29MWh (29,000kWh) per year from solar (gross not net). What I attached is my inverter outputs. Basically my solar acts like a bank for the power in the summer and in the winter when my geothermal is really kicking in takes the power out of the account. From November to April...

  • Post in thread: psa: Chargeverter is LOUD

    That's great to know about the slight audible noise. I have so many other noises going on I know that would never be noticed. I know the exact noise your talking about though. I mean in context I can hear the chargverter OVER an RV AC which is ridiculous.
  • Post in thread: psa: Chargeverter is LOUD

    I believe they all say built in potentiometer's. What's interesting is the HEP-1000-48 still de-rates' quite a bit as well. I do like the fact that the HEP series can be programmed as a charger as well vs a power supply.
  • Post in thread: NYSERDA

    Basically here is the diagram I have below. I do wonder about possibly up sizing the inverter(s) possibly? I just don't know how much it buys though. Upsize the 6kW to 7kW and 5kW to 6kW. Max input on my 6kW is right around 6.8kW and Max on the 5kW is 5.43kW input. With efficiencies I maybe...
  • Post in thread: NYSERDA

    A few answers on this. Some of which i have pondered as well. 1) I do use the ground loops in the summer for air conditioning with geothermal. So pumping heat in the summer would hurt them. 2) I have thought of this for charging. And have also found out my job offers reasonably low rates for...
  • Post in thread: 48 volt solar set up for 50 amp RV

    1) Absolutely get batteries that communicate. I am planning on hopefully writing my own protocol from my shunt to help me with this. I only did this since I had two lithium ion batteries from before when I just had an inverter on my 30a 120V RV. So buying two more wasn't much of a stretch. 2) I...
  • Post in thread: Server Rack Eco-Worthy 48v 100ah and EG4 6000xp comms.

    Thank you. That is extremely helpful. So the inverters can do closed loop communications with it and it is largely just plug and play then?
  • Post in thread: RV build

    So I don't have any issues with over heating in that space in fairness though it's in a main living area so typically the AC would be on which definitely helps cool the unit. It also depends on what mode you're in with the converter. A simple passthrough with shore power tends to keep the unit...
  • Post in thread: EG4 6000XP Neutral-Ground Bonding

    I traditionally use bonding plugs on the generator as well. It would be great if the 6000xp had an option like this: 1) incoming AC power detected removed bonding wire. 2) No AC input bond the neutral and ground. To me it would be a simple software fix.
  • Post in thread: Another RV thread

    In my previous RV I had the inverter installed under the kitchen sink area raised up on a platform. This was mainly invented unless the cabinet door was open (rare). You could here the fans but over the noise of everything else it was never an issue. I never had an issue and maybe it was so...
  • Post in thread: RV solar and generator battery charging advice requested

    I posted about my build in a thread here: RV build It looks similar to what you're looking for and I am using most of the equipment you have listed. I have a 38' tow behind trailer just as an FYI.
  • Post in thread: psa: Chargeverter is LOUD

    Supply looks great. Did you purchase that programming module (I assume it can use it like the HEP-2300) or are you planning on doing it manually? @Will Prowse it would be cool to see some of these Mean Well chargers as a review
  • Post in thread: NYSERDA

    I am also just south of Syracuse as well in Pompey. Initially a contractor installed the initial system and filed the paperwork and everything. As far from a power consumption standpoint I use probably 36,000kWh (36MWh) give or take during the year since everything I run is electric including...
  • Post in thread: Another RV thread

    Trying to figure out where to mount the converter and battery in the trailer. The electrical box is under the ward / pantry towards the back of the trailer. Initially was thinking under the king bed for the batteries but that inverter (6000xp)is not going to fit. It is a 2018 keystone cougar...
  • Post in thread: Another RV thread

    I have upgraded my travel trailer to a larger 38' travel trailer (2x ACs now) with a 50 amp service vs the 30 amp service I had in the past. In my old TT I had a manual transfer switch, 2x 12V batteries lithium, a 3KW inverter and a spare 12V battery charger that charged the lithium ion...

    Yup. I traded my half ton for a dually really quick on my last trailer that wasn't nearly as big. Honestly been thinking about this. Just wasn't sure how well it would it do if it ever had the chance to get exposed to the rain. I think unlikely but I still think it's possible. I do like that it...
  • Post in thread: Another RV thread

    I would love to put the batteries under the bed. There is some room under the pantry where I can put stuff but there is not that much space. I could possibly do it in the back of a cabinet but I do worry lack of airflow. My old camper I had a smaller inverter under a cabinet and it got hot. I...

    Thinking more and more about this I am heavily leaning towards a 48V system especially looking at Will's new video and his mobile setup. https://www.mobile-solarpower.com/mobile-48v-system.html I was initially like mentioned in this using the EG6548XP but I am worried with the extremely high...
  • Post in thread: Another RV thread

    Has anyone actually measured the EG4 6000xp. I did some preliminary measurements in the trailer today and I might have a tougher time fitting it somewhere than I thought. Is it truly 25.5"x18"x5.25" as it says on the spec sheet? I seem to be very close in one or two of the dimensions quite a...
  • Post in thread: Another RV thread

    The price above 50/60amp MPPT gets very expensive quickly into the $400+ range. Basically it looks like I will be at $500+ already and the AIO allow higher voltages. Basically 12V at 1500W is a lot of current.
  • Post in thread: Another RV thread

    I was definitely going to keep them separate. The split phase and regular 120V outlet. 120V would go to a battery charger to power the RV and the split phase would just go to the AIO. The issue is where the power cord is right now is in the back corner of the RV next to the entertainment center...
  • Post in thread: RV roof angle 6+" curve

    So are you leaving walking room between the panels or on the sides of the panel. Do you have a good picture of what you did?
  • Post in thread: Another RV thread

    So the one difference is I got be able to hand a 240V input or a 120V input. That is why I was debating on putting the transfer switch in. As far as power is concerned I probably am about 1 AC based on the battery just due to the simple fact I think I will kill the battery too quickly otherwise...
  • Post in thread: NYSERDA

    That makes sense. I think I just need to do some math on what I would need. I was just trying to see if I could dual use the batteries as a generator if power goes down. My diagram is a bit older when I was looking more at battery backup as a generator when the grid went down.
  • Post in thread: Another RV thread

    Well I think I found where I want to put the inverter. I have a large area behind the TV where it should easily mount. I am wondering if I have room to put the batteries next to the fireplace in the back. Two on each side. The only thing I don't like is this would all be on a slide. The fridge...
  • Post in thread: NYSERDA

    I agree with you. I honestly never thought of higher voltage batteries like that but it makes a lot of sense especially when you get to whole house backup level. There is always a trade off with system size and voltage level most of the time.

    So which inverter series do you like more? I got to be mindful of minimum voltage for the mppt. Right now I was going to go with 5x of the suntech STP295 watt panels in series. Open circuit is 45.1V and 35.7V at max current. I may do more panels but right now I was going to start here. *Edit*...
  • Post in thread: 50-amp 48v RV Question

    I am doing a very similar setup. The plan is to put a chargverter input in case I have a 120V feed or need to power it off the generator. I plan on starting a build thread soon. I do like the idea of a separate input for the inverter. Might be cheaper than running a longer length of wire...

    I think I agree with you 100%. I was doing the math while I was posting.
  • Post in thread: NYSERDA

    Reading into the Sol-ark it looks like it would have exactly what I would need and looks like I could do the vast majority of it with one Sol-Ark. Biggest issue I see is that it is limited to 19.2kW AC solar input and I am at 23kW already. So it would look like I would need two of them minimum...
  • Post in thread: Server Rack Eco-Worthy 48v 100ah and EG4 6000xp comms.

  • Post in thread: RV roof angle 6+" curve

    Thanks for the help and pictures. That's probably what I will end up doing. I was looking at beveled (angles) washers to level things out as well. Do you think it's possible to mount the panels length wise and just mount to the unistrut that way in 4 spots along the channel or better to add...
  • Post in thread: NYSERDA

    That is a ton of battery power in the video. That had to cost a fortune. In an ideal world it would be great if I could do both battery backup and grid export all in one. I guess I would need to figure out how the other solar would work in this configuration as well with the grid tie...
  • Post in thread: 48 volt solar set up for 50 amp RV

    I posted my build here. I went with the EG6000XP and had really good luck with it this far. I am able to run both ACs on it with shore power and one for about an hour with my battery. I camp in the Northeast and Midwest largely in wooded areas so my solar isn't as effective but I don't need AC...
  • Post in thread: NYSERDA

    Understood. I was hoping not to have to parallel two converters just due to cost. On the other hand it gives you quite a bit of power for backup without stressing converters too much.
  • Post in thread: Another RV thread

    Can you elaborate on this? ATS = auto transfer switch? or auto transformer ? Do you have a diagram?
  • Post in thread: Another RV thread

    Thank you for all the advice. I need to do more research on this too on the AIO. I just wanted to make sure it makes sense from a cost perspective to look at an AIO with MPPT vs just getting two or three separate controllers. It seems like the consensus is a yes. Any thoughts on what to do...
  • Post in thread: NYSERDA

    I thought of that. It is a $20 connection fee per month for another meter. The only logical place to put it to is about 1/4 mile from the road (Garage) so I am sure it would cost quite a bit.

  • Post in thread: Another RV thread

    The trailer is split phase power or has the ability to do it. So how do you handle the jumpering of the 50Amp service? In my ideal situation I would be able to use the 50A straight from the plug or use the jumpered 30A plug for the 120 from the generator. I think if I go with the bigger 6000W...

About $400 difference but the HEP is for harsh environments, already has the heatsink etc. May start with one and go from there if it works. Just going to do some more...
  • Post in thread: psa: Chargeverter is LOUD

    So does the audible whine happen when it is in parallel only or when they are alone as well?
  • Post in thread: Another RV thread

    Is there any reason to not get the bigger 5kW versions vs the 3kW if doing 48? I don't see many 3kW with the higher power. Guess would be ideal power consumption possibly? I guess it would be for the one time we run a microwave while the AC would be on for some headroom.
  • Post in thread: EG6000XP

    Thank you. I will try that. Is there a planned firmware upgrade to add that functionality? Also I see the AC detect goes down to 90V input for faults. Does that mean it potentially could run on single phase input vs split phase?
  • Post in thread: Another RV thread

    Well I went and took some measurements and I don't think my initial solution is going to work where to mount the inverter. The inverter is 18×25.5×5.25 inches and max kitchen is 20 inches. The first photo shows the small kitchen. Not sure I want things in the kids bedroom too accessible either...
  • Post in thread: NYSERDA

    Thinking about this more I probably should detach one of the sunny boy inverters (5 or 6kW) and put it to the PV input of this on the Sol-Ark. This gets me roughly around 17-18kW for AC coupled and then run the additional panels to the Sol-Ark for more PV input. I can get an additional 12-13kW...

    So if you have a generator input will it charge the battery fully when the other main input is not available based on the generator settings in the manual? Just wanted to make sure if I set it to charge to 100% on the generator it would do that and then discharge from the battery afterwards if...
  • Post in thread: Another RV thread

    The way I would consider this would be sort of how motors work. In this case it would be comparing a traditional AC type motor vs a brushless system which is vastly more efficient. Typically the brushless push way more air with way less power with fans. I imagine these work more like a mini...
  • Post in thread: psa: Chargeverter is LOUD

    I have chargverter 2 and how loud it is dependent on voltage of the charger. So charging at a higher voltage makes it louder. So as your battery gets closer to full charge and lighter load the fan gets louder which is quite annoying. For comparison I have an EG4 6000XP next to it and it is...

    This is going to have to be my approach at this point. I have a bluetooth shunt currently but I got to see what it is rated for. Do you have any pictures on how they are mounted in the vehicle?

    I was looking at mouser today at some other meanwell supplies. I think I saw a 1000W version around $230. Meanwell I wonder possibly getting two of them and maybe doing two dedicated 15A(with breakers) outlets on a 30A plug or something. I am going to do more searching though. Ideally I...
  • Post in thread: psa: Chargeverter is LOUD

    I think it is but the cord doesn't look like it would handle it so I don't know how they get to 5kVA unless it was a 240V input. I don't know exactly the transformer is tapped. Thinking more about it I don't care if there is a fan, just as long as it isn't extremely loud. If quieter than the...
  • Post in thread: Another RV thread

    That makes complete sense. I think I wasn't grasping the 6500ex vs 6000xp initially until I went further digging into things. I will look into a charger. Any recommendations? I may have one sitting around at home possibly. Also have a few 12v chargers and could possibly always use a DC/DC...
  • Post in thread: Another RV thread

    I love it. I am actually thinking of using the 50A as a second split phase as well. I can use the same plug and send it to a battery charger that is a universal input (chargeverter) and if I just want to quickly charge the battery I could use that. Only question is running it to my truck while...

  • Post in thread: Another RV thread

    Your design is making more and more sense now that I keep copying it further. I do have another 48V power supply that is 10A. That is a .1c charge rate. I am guessing I still want a chargverter to charge quickly if needed.
  • Post in thread: Another RV thread

    For some reason I kept confusing the EG4 6000XP (split phase) vs. the 6500XP (120v) So are you guaranteeing the Split phase input on the rv? The idle consumption of the 6000xp seems much more palatable vs the 6500xp at 80W plus.
