I recently acquired a Phoenix Combi (for a good deal) 12V / 1600W / 75A inverter and charger for my boat . After going through the user manual, I noticed that the manufacturer recommends using a 300-600Ah battery with this unit. However, I believe that a 300Ah battery would be overkill for my intended usage.
I plan to use the inverter for basic power needs on my boat, such as running some lights, charging small electronics, and possibly a small refrigerator. A 200Ah battery seems more suitable for my requirements and would also be a more cost-effective option for me.
My question is, would using a 200Ah battery instead of the recommended 300-600Ah battery cause any issues with the inverter's performance or potential battery damage? (overcharging) I want to ensure that I have a reliable power setup without overspending on an unnecessarily large battery.
I understand that using a smaller capacity battery may result in shorter runtime, but as long as it can handle my modest power demands, I would be satisfied. I want to make sure I'm not overlooking any potential problems or safety concerns by deviating from the manufacturer's recommendations.
Has anyone had experience using a lower capacity battery with a similar inverter/charger setup? Any advice, insights, or recommendations would be greatly appreciated.
Thank you in advance for your help!
