Re: Controller upgrade (bad panels?)
Solar panels have ~36x 0.50 VDC (Vmp per cell) cells in series. And there are usually 2-3 "bypass diodes" that will send current "around" any bad cells, shaded cells, or broken co…1 · -
Re: How bad is 75a charger on a 100bms bat? 12v 200ah 2560wh lifepo4
Lithium Ion batteries typically have a very flat charging curve from beginning to near 100% State of Charge... So, they should draw 100% of the charger's rated current (assuming charging voltage is c…1 · -
Re: Percentages and voltage of lifepo4
BMS "cutoffs" are really intended to stop "catastrophic" battery damage (and risk of fire). Your system should not use the BMS "cufoffs" (voltage/temperature/current/SoC…2 · -
Re: Best and fastest lifepo4 charger
It seems that your 200 AH battery will take 100 Amps for 120 minutes (2 hours)... To figure out what size Genset... In general, I would suggest that you load your Genset to 50% (for fuel efficiency) …1 · -
Re: Setting up Litime 60A MPPT
Litime finally got back. The 0 to 247 number "means address code of the controller and has no influence" ... ? Ha. Was confusing... Load is the light as we found out before they responded. …1 · -
Re: Batteries not able to reach EQ voltage
No practical experience with an FXR3048A-01. Maybe some else will be able to answer that. I don't use a generator. Either the charge controller set to EQ Vdc or the Inverter set to EQ Vdc, but not bo…1 · -
Re: Inverter setup
I did not want to start with the "full price" inverter in the discussion... The cost for that 70lbs of copper and iron (plus electrics, engineering, mfg., etc.) is not cheap ($1,000 vs $4,0…1 · -
Re: How many watts should my PV pull in during full sun
Don't expect more than 75 - 80% from your panels even at solar noon. As your panels warm up, they produce less than rated power. On a COLD sunny day you can actually get more than rated power.2 · -
Re: Kohler 20 kw nightmare
AFCI (Arc Fault Circuit Interrupters) detect an "arc fault" (sustained arcing on AC wiring) from monitoring the Radio Frequency (and other?) electrical noise on the AC lines. And one reason…1 · -
Re: What's a good LifePo4 charger?
I have a small 12v LiTime battery and purchased the small charger for it. A quick look shows LiTime makes an 80A charger as well. I would investigate the charger and its power requirements to run fro…1 ·
