How much generator needs to run if I have DC 3.1kw load@48 V , 700AH lithium banks and 13 KW solar, in off grid telecom site?
Hi @inam, that highly depends on your PV array and the part of the world it is installed, direction and angle it’s facing, potential shading etc.
There are tools that can help you predict your solar production. I like to use the following: https://re.jrc.ec.europa.eu/pvg_tools/en/
Hi@philipp, my question is related to energy margins we can consider yield is 4. my calculation is that 3.1 kw would consume 74 kwhrs in 24 hours for that i have already 13 kw solar i.e approximately 52 kwhrs would be generated from solar then rest 22 kwhrs would be supplied by generator. i have 700 AH lithium back up as well , which would sustain the load for 8 hours at 80 percent dod… my question is related to energy planning not something about calculator.
