Got a heck of a deal on four MPP solar LV 6548s They were pulled from the guy's system to upgrade to an 18,000 W EG4 I got them for a pretty good price... Came with all the parallel cables and such I didn't actually get around to hooking them up... Though he was willing to hook them up for...

I recently installed solar panels on my shed the shed is really small about 5 ftw by 7 ft I also built action effectively double d available space for solar panels The plan is to have, 3 rows of 3, for a total of 2250 watts

So on a group I'm in somebody posted what they claimed was an 80000 watt car subwoofer system... Naturally I pointed out the absurdity of this First I started by taking 80,000 watts and dividing that by 13.8 volts which works out to nearly 5,800 amps Then I explained that a single 4/0 gauge...

Ok heres the deal Over a year ago I built a huge TEMPORARY 4P4S battery SHORT STORY The battery is falling out of balance as we approach 100% SOC... 1 cell block will creep higher than the others (the highest I saw was about just over two tenths of a volt These cells have been in service...

I am getting ready to build a house... we are are used to not using huge amounts of power, we have been living off grid in our RV(see RV specs below) I am planning to use Santan Solar 250w panels, between 4000w and 8000w(I figure they are cheap enough) as well as DIY 16s1p Eve Cells 280ah and...

Hey guys and gals Hope everybody's doing well I'm getting ready to add a second inverter to my existing system... Now this is a temporary install... I will post system specs at the bottom Currently, I have 1/0 gauge wire coming off of the batteries and BMS and then running to a 350 amp blue...

Okay so you can see my system specs in the signature I'm somewhat concerned that there might be some issues with keeping the batteries properly charged while I am gone... I certainly don't want to run my lead acid batteries down to nothing... If for some reason you can't see them I have an...

So I have 4x Duracell GC2 FLA 6volt batteries... I was thinking that since they have some age it might be a good idea to test their capacity... I was thinking that a simple way to do this would be to split the batteries in to a pair of 2s, rather than testing them 2s2p... My thought there is...

Maybe it is just as simple as grid power, but I am not for sure...I mean CAN a 220v simply be split down to a pair of 110v? Or does it depend on the specific manufacture? It looks like some of them you simply add a second 110v inverter, allowing you 110v x2 and 220v x1... trying to understand...

So I've been having some problems with blowing relatively high current anl fuses when my air conditioner fires up for the second cycle I was running it by a friend of mine who does a lot of mobile installs nothing normally and quite this high of amperage but he asked if I was using any type of...

It's been several days without sunlight... So I have been trying to come up with a faster way to charge batteries when I'm using generator Currently I have a large 4s battery bank. About 20 kWh My Aims power inverter has a built in charger... About 85 amps I was thinking maybe I could...

So the wife and I purchased an RV, we sold our house and decided to buy a small piece of property we've been living there for a little while now and the RV actually came with solar power when we bought it but it was pretty inadequate for our goals it's still not where we need it to be but it...

So I've got a bit of an issue... I need to start bringing my new system online... Need to build the new battery... I need to do all the things... Lol. I need to test the inverter. Here's the problem... I don't have a place to put the new solar panels yet However currently I have one system...

Where would you purchase cells from these days?

Just curious... Will 16s lifepo4 be too much voltage for my MPP LVX6048? I have read through the manual and really couldn't get a clear answer?

I was installing a solar setup in an off-grid RV for a local guy a few days ago We went with a 24 volt, 100 amp hour lithium iron phosphate battery, a 3000 watt / 60 amp MPPT all in one charge controller and 1200 w of China solar Because this was an RV he still had many items that ran off of...

What's the trick to fitting 0 gauge wire on this breaker It's so close...

I am wanting a little help to predict the results of mixing the following battery packs 1.) 4s2p, 230ah Eve cells, 200 amp BMS (about 5.9 kWh) 2.) 4s4p, 304ah Eve cells, 200 amp BMS (about 15.6 kWh) Total would be about 21.5 kWh (the smaller battery would be about 27% of the overall...

I am getting ready to build my new battery. 8 pcs - EVE LF230 230Ah 3.2V Lifepo4 Battery, @ $108.50 per cell =$868 2 pcs JBD 12V 200A BMS with Bluetooth @ $120.00 per unit = $240 busbar and screws(8pcs busbar and 16pcs nuts) FREE. ? total = $1108 The plan is to build 2, 12v batteries, each...

So I've been looking for an easy way to distribute power and or splice cabling ... In the past what I would do if I needed a splice cabling and a pinch is put a nice crimp connector on either end connect the crimps to each other and put a bolt through it of course insulating it with either...

I am getting ready to build a pair of Eve 230ah 4s batteries... Curious about using kapton Tape vs a wood skid with all thread

This is something I was thinking about so a while back I ran into a problem we're the previous owner of my RV had installed terminals with half inch holes.. the problem is the stud that it was mounting to was actually quite small and was only one quarter inch.. as a result these connections were...

So I have been in the process of bringing the voltage up on a 4p4s, 304 amp hour battery Started out at 3.3 volts when the cells were delivered and I'm really only getting between 13 and 18 amps when the BMS is hooked up Since I purchased two bms's I thought maybe it was a limitation of the...

I can't seem to figure out the heater function on the JBD 4s 200a BMS...

In the past when I put batteries together I would top balance them at 3.65 volts.. But my question is should they be balanced at 3.65 volts if I intend to run at 3.45 volts? Or if I'm intending to operate at 3.45 volt should I do my top balance at 3.45 volts... My guess is 3.65 Just curious...

So I'm still working on my house... The house would be completely off-grid I thought I had it pretty well figured out but now I have some concerns Originally I purchased the MPP solar LVX 6048 I thought this would be a great unit and then I could just keep adding to it But lately I've been...

Just curious if you guys could take a quick look at my solar charge controller and BMS settings please want to make sure that I'm not messing stuff up

I'm getting ready to start planning my build with 4, MPP solar lv6048's These are 48 volt, 6500 watts So I figured each unit will pull up to 160 amps 6500w ÷ 0.85 = 7647w 7647w ÷ 48v = 159 amps So we could call that 160 amps per unit... I think this is a conservative rating as the unit is...

I am planning a big off grid system... I'm trying to figure out the best way to configure the panels I have with the solar charge controllers that I have.. I will be running a 16s, 304ah lifepo4 battery with 200a BMS Be running two solar charge controllers -Inverter AIO MPP LVX6048 (up to 450v...

A young couple moved in near me in our small lake community... They plan to build a tiny house in the spring... For now they are trying to survive on a small marine battery, 100 watt solar panel and renology own SCC... Oh yeah and a 1000 watt pure sine wave inverter... All this is installed...
