Using IP22 Charger in power supply mode

Q&A and troubleshooting

Hi, I am using an IP22 12/30 to charge a 200amp LFP04 battery. It works well. However I want to leave it connected to shore power to power the fridge. The fridge draws around 4.5amps when cycled on, in a 24 hour period it will average an amp per hour.

Is it safer/better to use ‘power supply’ mode when the boat is unattended or should I simply leave it in ‘charge’ mode to maintain the battery at ‘float’ level and supply intermittent power to the fridge?
I don’t usually leave the battery on charge when I’m not on board for long periods, for short periods - a few hours - I dial it down to 15 amps. Just being cautious.

So to use ‘Power Supply’ or not to use ‘Power Supply’ to keep the beer cold?
Thanks in advance

Leaving it in charge mode (with the right profile for your battery) will do the right thing.

Drink all the beer before leaving and you won’t care anymore… :smile:
Or follow Gregor’s advice.
