I have a boat with 2 battery banks, i have 2 solar panels (one for each bank) wired to 2 different SmartSolar 75/15 controllers. I also have a VictronBSC ip22 HQ22263HTDE battery charger and the engine also charges the battery, the battery charger is not on when engine is running but the solar are connected while the battery charger is on, Is that ok or do i need to turn off solar when charger or engine is running ?
Asked and answered many times. All chargers have a voltage control, so if they can supply more current together than the battery needs then one or more of them will regulate down to maintain the required voltage. You will find one ends up being the first one to regulate back based on minor discrepancies in measured voltage. You can set the solar charge voltages 0.1V higher to give this priority. I have run alternator, solar and mains charging at the same time.
Thank you that was my assumption
