I have a grid tied (Enphase) system on my home and decided I wanted to add batteries to run my fridge and small appliances for emergencies. My solar contractor wanted 8-10 grand for budget Enphase battery system. This was way to much for what wanted so this was my compromise. 800 watts of solar...

I just received a pair of Chins 12.8v 280 ah batteries. The both read 13.19v. Should I charge them individually to 100% or just install them (parallel) as they are.

I just purchased a Bourgerv 60amp controller. The specs on the voltage are 100V (95V protection, 90V recovery). Can someone explain to me what this actually means. Thanks, 8mm

I'm looking at buying 4 chins 12v 100ah batteries. The maximum charge current is 50 amps. Is this per battery and does the allowable charge current go up as you add batteries in parallel ?

My system will be unattended for usually 3 but up to 6 months. My plan is to use a 365 day timer to charge every 90 days for a specified time period. ? How long should I charge (four) 12v 100ah in parallel with a 10-15 amp charger. ? which if any 110V 10-15 amp charger will let me adjust the...

I plan on using 4 - 100ah 12v lifepo4 batteries in parallel for my backup power. What would be the maximum / appropriate size 110v battery charger current ? I would like to have 800 watts of solar, would 80amp MPPT controller charge current be to high ? Thanks, Richard

I just had an Enphase Grid Tied system installed on my Florida home. I have 11 - 405 watt REC panels with IQ8A micro inverters on one branch. I am confused about the output current and total energy in the system. The combiner box and main panel only have one 20amp breaker. I questioned the...

I would prefer longevity over peak performance in my LiFePo4 batteries. Would using lets say an AGM1 profile (14.1-13.4) extend the life of my batteris in the long run. ??

Back in May I decided if I was going to enjoy my retirement with Covid-19 I needed a Off Grid Van. Dec 10th, 1000 hrs labor later it was complete. It would not have been possible without Forums and Youtube.

The Renogy web site as well as the online manual indicate installing a fuse between the alternator and vehicle battery. (20a dc to dc charger). This seems insane to me, am I missing something. This image is from the renogy web site. NOTE: the Renogy 50a MPPT controller with alt. charger...

I would like to monitor the system, any suggestions on shunts and displays would be appreciated.

I was going toward a series set up so my system could charge in low light conditions (early AM or heavy Clouds) , when the panel voltage output was low. I assumed that 4 panels at 4volts (16V) would still be able to charge the batteries. Where in parallel the panels would be useless until the...

I want to build a 400 watt solar system for my van. (300 amp hour Lithium). I want alternator charging as well as grid plugin / generator charging. Am I asking for to much. ? This is what i was thinking about using. 400 Watt Solar Package w/ Alternator Charging example off the Mobile Solar...
