Busy learning as I go here in load shedding South Africa so any help would be much apricate:)
I will try keep things as simple as possible so here goes:
I have a Gel battery with a 200 ah capacity hooked up to a 1600w pure sine wave inverter. I bought a 500a smart shunt in order to regulate my usage and monitor the vaults.
The question I have regards the voltage reading of the battery dipping substantiality when I apply a load of around 300w. Fully charged I have the battery reading around 13.61v without a power draw exceeding 20w. When the load increases to around 250w the battery takes 30 or so minutes to drop below 12.1 (at which point I cut the load to ensure I don't drain it past dod) just to have the battery jump back up to a range of 12.5v without a load and no charge applied
Am I doing my battery harm by dropping the vaults so low under load?
What is the lowest voltage I should allow under full load?
The vaults have never dropped below 12.3v while no load is being applied? Would it be safe for me to keep using the system under load if I know when i cut the load it returns to thee "safe" operation vaults of the gel battery?
Any help would be appreciated,
