Be careful with the BMS assumption... Some will shut the battery off (over voltage, under voltage, over current, etc.)... Some will communicate with your controller(s)/inverters/etc. and send them th…2 · -
Re: Newbie looking for a simple solution
You need to find a Vmp ~= 35-49 VDC. Many "24 volt" panels have Vmp~30 VDC. That is too low of voltage. Vmp falls by almost 20% on hot days under full sun. Need the higher voltage to quickl…1 · -
Re: Help connecting inverter to sub panel with ATS
Big Cali, The answers really depend on the details of your needs/installation. For example, there are AC Off Grid Inverters that have their own internal transfer switch--And you can take a standard A…1 · -
Re: Newbie looking for a simple solution
OK, the min/max daily (or over night) discharge I would suggest: * 10 AH * 1/2 days storage * 0.50 max discharge = 2.5 AH @ 12 volts (2 days of storage, and less than "full discharge" of ba…1 ·
