I ordered a "Great deal"on batteries from ali - 12 v0lt 50 ah I got 6 aa batteries in a 12 volt battery pack. took forever to get my money back

I have to suggest building 8 x 8 instead It works easier and is just nicer to have that extra room

These were from aliexpress, 50ah samsung Li-ion battery packs with 6 18650 batteries inside. Ali kept denying my claim until I said the technology does not exist to put 50ah in a pack that size

20% off was $170 now $136 looks like a decent deal for a ground mount rack...

Close out on this Renogy inverter charger$499.99 - coupon code "QUAN" - $24.99 = $475 I'm not a big fan of Renogy, But I need to replace the one in my van. I figured a 1 year warranty from Renogy, then an additional 2 years from my credit card. works for me...

I dumped all the 12 volt lighting at my cabin years ago. I now use a separate small inverter switched at the door. 120 volt led are so much handier

I'm not a big fan of renogy, but I have to say that my dc 50 has worked perfectly for 2 1/2 years.. It outputs 50amps MAX, solar OR alternator. Or Up TO 25 amps each from both at once If solar is producing any power at all, The alternator is limited to 25 amps.

These are 3.7v NMC lithium.

That AIO is 220vac output. if you are wanting 110 volts,?? you will need an auto-transformer

200 amp pass thru looks promising, no price on it tho??

That max solar juice is just hypothetical. If it's not being used (and it's not) It's not being generated. I've got my dc50 hidden behind a wall where it doesn't get any ventilation, and it hasn't failed

They appear expensive ??? here's a couple for sale Denver area. https://denver.craigslist.org/grd/d/littleton-tamarack-pole-mount-solar/7658813815.html

It looks like your bms has shut it down. when this happens to mine, I jump 12 volts to it and it comes right back on.

Not yet mentioned, is 3,33 volts per cell 13 volts for the pack, is right at the charging knee. it could be as little as about 25% charged, or it could be 75% charged. I've seen people think their system wasn't working correctly. It takes a while to get past that 3.3

for wiring your panels to the combiner box, 6 arrays at 3 panels each. connect positive to negative in each array. then connect 3 arrays positive to positive neg - neg. do this twice. that growatt has 2 mppt connections for this 30 amps is the limit for standard 10 gauge solar wire 3 x 10.74...

I've had great experiences on Aliexpress. Most have gone off without a hitch, but the few that were con jobs, Ali refunded for me. Shipping takes a while, but if you can wait, tthere are great deals to be had.

And, Where are you located?

Not a JK, but a generic smart bms https://batteryhookup.com/products/7s-21s-24v-75v-300a-lithium-ion-bms

This inverter GSL-H-12KLV-US has a 200 amp pass thru. It's UL listed and on the California approved list. It should allow you to connect your entire panel. follow this thread for more info...

I think the component needed is an 'isolation transformer". It splits into 120 volt. I didn't look, but there is probably a split phase 120/120 also

New coupon code is "DIY" 5% off

I may have over paid. These were $320 for 4 ...$80 each. I have started cutting these into 14s ... 48 volt packs. i have ordered bms and mppt charge controllers. also traded a $2000 car for 30 375 watt mission solar panels. Now I need to figure out where to put them. They will take up a LOT of...
