Well I am trying to properly size battery bank for my home. 10000kwh per year average use. I did the online calculator at unbound it says I need 37kwh battery bank on 833-900kwh used a month:unsure:. 900/30 is 30kwh why is it adding 7kwh to the factoring? inverter loss? cloudy days? I am...

I know this has been discussed and Will made a video but I can not find it for the life of me. I want to maximize life and use of the battery and take the 80% of power available from the eg4 battery before recharging via solar or grid. how do I accomplish this? what are the settings I need...

my questions about 2 different inverters using/drawing power from 1 large battery bank each one on its own panel. can this be done?? Well I am looking at getting real close to getting everything I need to take home off the local power company. 10000kw a year avg should be 6.6kw array that I...

well I am trying to save some $$ and build my own 48v 280ah battery vs 3 more eg4 batteries. but want to be able to monitor it with my eg4 inverter if possible . I have 1 eg4 5.1 kw battery already just want and will need 300ah minimum for power needs. Is there a way to have both batteries...

was looking at those units as they seem to be rock solid for sure. 2 of them might be able to cover my needs. a good 50amps 120v per leg & being consensus of power use and not having to many items on at 1 time should be easy enough. now to get another 300AH of batteries

I am looking at going away from my local power company as much as possible & the costs. I have done the math 10000kw a year avg use needs a 6.64kw solar array and 15kw in batteries minimum to off set my use in Oklahoma. Currently I have 1 48v 5.1 eg4 rack battery bought for another project...

Thank you all

https://www.santansolar.com/product/unused-first-solar-460w-solar-panel/ Claiming 188v from a single panel roflmao. Yes or no true or false is this possible???

I have starlink it is fantastic & im not even in a serviced area LOL. 60 megs down all day. I shunt with wifi and should be easy to monitor. I have the eg4 not installed yet and got 1 rack battery going to have 3 in total. I want to monitor mine for sure & with the starlink it makes it possible...

No I'll have eg4 100ah rack unit and then add 1 or 2 more as $$ allows. Made the decision for eg4 Aio and battery to make easy all in series on panels so no issues on dcv. Just not happy with the standby use 70 watts maybe 40 if lucky. Going drive and get it's cheaper then shipping even with...

that's a added $400 for a 200v controller, on top of the AIO I am not liking this situation at all, there has to be a easier way to make this work. a better AIO unit or something. there new 6.5 egs AIO comes on at 60v not 120 v like the 3k unit WTH signature solar how about a consistent mppt...

but then I am out 480 watts of power that won't cut it for me I would rather take the risk of frying a AIO then not getting my wattage of 2400. I am trying to run air conditioner on my solar power. need at least 2k watts. if I got with the ES model it has 250v max but starts at 120v but will...

Well crap I need keepnthe dcv high enough for a 3k inverter. Maybe the 250v es unit and all 10 panels or 11 panels will work.

Love that information . Talk about smart importing and saving money. I'm sure big business does this every day

I am located in Oklahoma but plan on taking the 5th wheel all over the country. so conditions will change on a regular basis when traveling. with the 5% added 142.17 VOC would be total on string of 5, yes extremely close to the 145 voc. I just don't see it ever hitting that high most panels...

I have been researching and asking questions & think I have come down to this setup, if it is all good in power and output please let me know. 1 Growatt 3k tl- lvm 48v, 145dc voc pv input , panels Newpowa 240watt voc 27.08 vmp23.32 in 2 strings of 5 VOC is 135.4v & 116.6VMP the manual says PV...

What brands and wattage panels are you using on your RV roofs? Not van roofs. Trying get idea of best panels under 36 inches wide. So far rich solar 200w and newpowa 240w. Both under 36 will work but wanted to hear what your using out there. Looking for over 2k on my roof Thank you ahead of time.

What panels are those ? And wattage? Please. I'm going with the eg4 and batteries for my 5th wheel. Making install way easier other then mounting panels ??. Still trying to decide on mount options. Voltage toy hauler 39ft. Any suggestions ate welcome. Have a wonderful evening.

I just watched it ??. Can you do a solar mppt test? ? To see when the unit actually starts producing power please ?. Hoping at 120v like it says if so. I'm ready to drive down 2 hours and buy it and 2 batteries for my 5th wheel ??. Thank you have a wonderful evening. Love learning and...

Ditto same here. $$ is not the issue. Want a nice unit the 500v makes it nice and easy for wiring. Just want to make sure it actually starts at 120v for the mppt before buying. When Will did a review on the new Growatt es model it took almost 180v I think to start up out of the 250v max. If not...

looking fwd to hearing what you think. I have been trying to decide on what inverter to go with the panels I like that are nupowa 240watt . under 36in wide 58in long great for RV roof. voltage has been my enemy on panels and AIO units. between Growatts old 3k lvm vs the new ES unit with 250v...

After lots of research looks like these will be a great fit for my 5th wheel roof for layout as there small I can fit them on each side easy. I am looking at these but would use any that fit good on the roof. under 36 inches wide is best to fit each side of the AC units, length is not so much...

wow thank you so much the chart is fantastic. I am still learning the combinations of panels. tons of room for panels on the roof even with 3 AC units & 3vents there all in center 39x8 roof , if I had nothing on sides IE bathroom vents, tv antenna I could fit 6 on 1 side alone? of course vents...

here is the Growatt it says 300vdc on front of the page but specs say 250VDC VOC https://www.growatt-america.com/show-42-641.html I will be calling them in morning for sure, wow just looked signature solar is there distributer in the USA. less then 4 hours from my house. for sure going less...

Well I am getting 1 day closer to purchasing everything I need going with the Growatt 3k lvm es unit will be the inverter with a max of 250vdc PV input. I need advice on panels I would like to get 2000watts or more on the 39ft RV roof but have 250v max & 18amps max capable can I/should I...

no 240v appliances just the 50amp shore power and 5500 onan connected to transfer switch giving me 120v x 2 legs for RV panel. I know most people go 3k inverter in each side of rv power panel so all outlets are powered. I was just trying to purchase a single unit that can give me 120v on each...

I posted before about the system I am trying to decide on proper parts for it & need help with that end. I am getting closer to making my purchase & want to make sure not to mess up. the ? is the Growatt 5k unit is 240v ac output. if it was hooked to a off grid home panel it would be the same...

Thank you for your kind advice in going bigger now for sure or dbl up on 1/0 if that would do it. Getting 3/0 connections to a battery seems tough what connects are you using? Just copper ends on wire to the threaded post??

all the research I have done says 1/0 - 0 gauge is fine for the 166 amps maximum continuous from a 2000watt inverter, the 300amps I spoke of is for surge capacity and in case of short for safety the fuse will let go thus saving the system and my home. it will be less then 7ft total round trip...

Broke down went the cheap route to start my setup before going all out with a all in 1 growatt and solar. I got the ps1003 go wise 2000watt inverter going to use a 300 amp anl fuse ,1/0 welding wire rated for insane amps per foot , 20 amp 110 breaker on output . I have got in my basket a 350...

Of course breakers and fuses where needed. The 265 units I was looking at are on signature solar there 36.7 VOC & 29.8 VMP not 60v voc . If I go 6 panels then I will be at 178 VMP & 220 VOC if this is sufficient then I will go that way. I should be just fine in cold with this.

I am a newbie I have been doing research and figuring out size of solar panels and battery I need for my RV. My ? is with a all in 1 inverter like the one I am looking at Growatt 3000 ES it has built in mppt. if I am using my own Daly BMS on my 48v DIY battery do I still just hook + & - to the...

I am needing 16 280ah cells and 150-200amp BMS. I'm building a 48v system for my RV going to go with a growatt 3000 for basic power needs and 1 AC unit.

I will not spend a dime $$ till I know power needs etc I know better. should be getting on roof soon at the dealership and plotting like you said it even before I buy it . going to probably make a rack system from uni-strut steel that's heavy or L track/airplane seat track aluminum & light...

well crap I thought it was residential at first but then found out it is a dual unit it's 18cubic foot :unsure:. I am surprised they consume so much power, I mean propane is simply heating ammonia & propane is cheap. for 12v it's low due to heating a element for the ammonia assuming that at...
