I need to come up with a plan around this error. What I have in mind is getting a UPS for a computer which has a battery backup in it good for 30 mins. When the fridge first kicks on, I want it to utilize the juice inside the UPS for its surge instead of the inverter. Anyone have any suggestions on which ones do this? I know not all UPS's allow you take a pull off the batteries if it has power coming in. Or maybe there's a better idea someone has to work around this issue?
Hi all.Been lurking for awhile.This site is a wealth of info.I have a small system that's been running about a year and a half.So far so good.I have 4 100watt panels wired in parallel feeding Tristar 45 charging 2 12 volt 50 AH agm batteries wired in parallel. A suresine 300 watt inverter gets some use.I now know these batteries should be 6 volt wired in series.I use max 500WH in the summer and almost nothing in winter--3 led lights and occasionally a trickle charger for lawn mower battery.Looks like I have enough charging capacity to upgrade to 6 volt 225 AH batteries.A couple days last summer my batteries got down to 12.2 volts--the reason for battery upgrade.Will my system work year round?.Do I have to exercise the batteries during winter or will they be happy just sitting with almost no DOD other than self discharge? I'm at 42 degrees latitude and the panels are angled at 22 degrees--roof pitch.I know the angle isn't good for winter but it is ok for summer when most of the energy will be used.I'm running a 12 volt cooler that uses 464 WH per day--manufacturer's number, not measured and 3 10 watt led lights,sometimes a small radio and a phone charger.If all goes well we would like to build a larger system.Thanks in advance for all opinions.
