Batery Maintain Mode

[mod37]

I'm in Baja now, but will head back north in a few weeks. I updated my solar system last November to 4-285 watt solar panels, a Midnight Classic 150 and 4- Rolls L16 428AH batteries. Everything has worked great. When I leave I will turn off my inverter but want to continue to keep the batteries sufficiently charged, without overcharging and using too much water. Ideas on what should I change in my settings?

I think Vic has suggested in the past that if you don't have a lot of loads on your system you can use the Skip Days feature to limit how often it does a full charging cycle.  Once it is in float you won't be using much water.  The thing is if batteries are in float for long time then the electrolyte can stratify so it is good to have a good absorb cycle to mix up the electrolyte. I think I have used Auto Equalize in the past every 10 days with equalize setpoint to Absorb voltage  but a longer absorb time . That would bubble the batteries longer and get things stirred up. And it also defeats the ending amps if you use that feature to stop regular absorb cycle.
