DIY totally by myself and I am over 60. Have 12 more panels on temporary mounts . 6 more mounted south like the the large array in an area that gets sun a little earlier and 6 more that get mainly west sun. Right now putting 9kw into batteries after running HVAC over night. Need more...

Another update: I installed the SureStart sot starter from Hyperengineering yesterday . It did even better than they claimed that it would! The inrush amps on stage one of the 2 stage scroll compressor 5 ton climate master Tranquility 30 unit was 99 to 103 amps on several measurements. After...

I just viewed that video and came here to post about it and you beat me to it. I wonder about malfunction of the "smart" part of the SPAN panel. If you have a malfunction you may be forced to replace it with a standard service panel or equivalent until the SPAN panel can be repaired or...

Yeah I didn't realize the mppt range was actually 5v lower than the LV5048 but it wouldn't effect my current array. I dont think just removing parallel hookup and reprogramming setup would be much to do at all to delete one of the split phase units maybe I am missing something . No rewiring...

One thing Solark is probably counting on right now is the Tax credit to make them look more comparable . The fact that not many installers will use the chines inverters also helps them. The added features and long warranty of the solar 12 (about same price as the 8) is one more reason BUT that...

The victrons might work if they have grid input and bypass also but then I would need a transformer for input and output both wouldn't I? I love the idea of 2 or three of the DETE units I could probably get by with just 2 units. If they are similar to the solark 8 or 12 that would be my...

To original poster. I have a 3 ton inverter heat pump that varies from30% to 130 % of 3 ton rating its a nordyne unit renamed for maytag taipan and Fridgidair among others mine is 21 or 22 seer and max draw is 11.9 amps and it ramps up slowly never going over this 11.9 amps. It also has dual...

I dont think you have to get a geothermal loop inspected but of course you do need septic inspected. Because of soil compaction etc you would likely need the geo loop several feet deeper than septic like 5-6 feet deeper. Same thought though. He has plenty of land just dig 2 sections of trenches...

Question: I was considering a pair of LV6548 s but since they are 120v each if one goes down you do not have 240v capability. A pair of LV6048 s are both split phase and the main differences I can see are the size and weight and 1,000 watt less max continuous power. Total price is similar...

Might not be as easy to sell as 6kw 120 volt system. I am trying to decide on the last pair before they are gone. Obviously a great deal but still think I could do what I need with 2 MPP LV6548 s and now researching the DEYE. I do like the grid blending and higher surge capability

That sounds really good. More and more people will be wanting to charge electric cars and using the cars designed to do so as backup batteries too. I can see 2 electric car families with one vehicle at home most of the time soaking up all the excess home PV and either swapping the stay at home...

Yes I think Alpine sells some DIY mini splits that are rebranded for them as Blueridge and likely made by Free or Madea. I see from your signature etc that you should know !! I have done a lot of DIY including geothermal install and mini splits etc. Interestingly I and my family also own 6...

Yes I am aware of that but a pair of lv6048 s are both split phase so if one goes out you still have 240 v split phase.

Just an update . I did measure the inrush current and its 99 amps. I ordered the hyper engineering 230v 16-32 FLA model soft start unit and hopefully it will be here in 10 days or less. I made it start in 2 stage also and higher I could get was 118A in reality it will never do this. I should...

Thats what I am struggling with getting at least one of his LV5048 s or all 3 and sell one or going ahead and change out to 2 LV6548 s now and ? add 2 more later another choice would be 2 LV6048s One could go with 2 or 3 LV6048 s if you can get by with 18 Kw or so continuous and you dont have...

You have received some very good advice. I am in a similar situation except in different area of country. I have 6500 square foot Dryvit home pretty well insulated. I have a pump and dump geothermal but may modify it to closed loop in future. Already had well and a ditch etc. You already made...

If it can be made to stick well try the liquid tape or maybe even Car undercoating spray.

Yes, I am well aware of the difference tilt makes. I have been tilting mine to various angles just to see what it does. The tilt from max watts to flat makes at least a 15% difference in mid winter. The problem with most tables etc is they dont account for the unavailability of sun at...

Remember you would also have fittings and depending on the unit the lines may have 1/4 inch and 1/2 inch lines plus 5/8 inch drain line plus 4 conductor 14 guage wire plus insulation. The larger and less efficient units like anything above 12,000 BTU may use 3/8 inch and 5/8 inch copper lines...

Yep wouldn't work in my area much at all due to high humidity and I suspect many similar areas. Generally a 12,000 BTU mini split once the area is cool may only use about 400-500 watts but of course that depends on the heat load of the RV. Remember you can also start with a fully charged...

BTW many inverters when placed in parallel still need to be attached to the same battery bank. I wanted to do this too but opted not to because of this. Of course you could use the switch like I mentioned above and get desired voltages in similar range without reprogramming each time but you...

I am not advocating this but there are people that maintain its better not to ground the pv panels on the basis that it actually attracts the lightning because its a less resistant path to ground that can still cause damage. They basically say it depends on surroundings such as tall trees near...

Very True as I said for Emergency use only. Make sure as code would require to have fire alarms and add co2 alarms even if off grid. Also you can always vent them and outside air intake etc.

No I mean the new model MPP LV 6048 here is a link to bay offering https://www.ebay.com/itm/6000w-48v-Split-phase-110v-220v-Solar-Inverter-80A-mppt-solar-charger-FREE-WIFI/274560618179?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

to Joe Ham Thanks for that information I have looked briefly at the link and will investigate further. Once 250v pv like the MPP 6548 it doesn't matter as much to me but it would be nice . I just would like it not to be around 100v which would increase the size wire I would need for pv...

yes I understand better now . You still might be able to use a voltage sensitive relay set up to Charge the Volt Pack first then when it reaches the desired voltage switch to the BYD pack. You might be able to get a little more out of the BYD pack by rewiring the weaker cells in parallel...

Answer to both above . The whole benefit of direct pv is not to use battery storage or need larger inverter or more batteries and also avoid the energy loss in conversion. You do NOT have to use special elements you just need an element that meets the correct resistance to work with your...

Yep thats exactly what I thought, especially since he has selling up to 4 of them (even though it says 4 or more only 4 are available.). I thought of doing that myself especially since I would probably need 2 of them. I would at least like to have one and get experience with it first though. I...

agreed but its also not just efficiency in the equation its installation simplicity in some cases portability or moveability etc. The ability to DIY installation or any other modifications required make any efficient system much more attractive though and is a value added to the property when...

Just a thought. I bought 42 300 watt panels from tartan this spring and the shipping to a fright terminal was $250. Your extra fuel costs and hassle factor may approach this amount anyway. The other thing to consider is the cost and room available and how easy it is to DIY. I chose 60 cell...
