Way more than a installer error. Nothing about your system was done correctly and the operator has no clue how to operate the system. You cannot go off-grid and be clueless ojn how everything operates. You especially have to know batteries inside and out. Or else you get what you got.

Example Red Flags as soon as you said you had 6000 watts on 24 volt batteries. Why do we know that is a problem, real simple the largest charge controler made is 80 amps. 80 amp charge controllers have the following power inputs vs battery voltage.

1000 watts @ 12 volts

2000 watts @ 24 volts

4000 watts @ 48 volts

6000 watts @ 60 volts.

The math is real damn simple 6th grade stuff with very easy formulas. Example how many watts can a 80 amp controller handle

More simple math To find how much current a given wattage into a given battery voltage is terrible complicated.

Battery Capacity takes 16 years of formal education in the USA or a 5th grader in any other country

So do some more hard math

No one can fix your problem, it was broke before you ever turned it on. You got away with it during longer days of Summer and Fall with no heat demand. You pushed it over the cliff from ignorance and idiots who designed and installed the system.

Dude I am just the messenger, You need a complete new system. Only thing you have that can be reused is the panels. That is you problem we cannot fix it nor can Tech Support. I suggest you educate yourself real fast. Start with the Stickies. When you replace the batteries get FLA batteries as they cost half a smuch and last twice as long as AGM. With FLA you can measure the specific gravity and actually tell what the real SOC is.

**Watts = Current x Battery Voltage.**Try it out with your 24 volt 60 amp Controller. 60 Amps x 24 volts = 1440 watts. So what is your problem with a 6000 watt panel, 24 volt battery, and 60 Amp Controller? I will tell you since you cannot do simple math 6000 watts does not equal 1440 watts. You are missing 6000 - 1440 watts =**4560 watts**More simple math To find how much current a given wattage into a given battery voltage is terrible complicated.

**Amps = Panel Wattage / Battery Voltage**. Try it with what you have and tell us what is wrong. 6000 watts / 24 volts =**250 Amps**. Your controller is a 60 amp controller. Is that a problem or not?Battery Capacity takes 16 years of formal education in the USA or a 5th grader in any other country

**Watt Hours = Battery Voltage x Amp Hours.**Try yours on for size 24 volts x 830 AH = 19,920 Watt Hours. You should use no more than 4000 watt hours in a day and never ever more than 10,000 watt hours before a complete recharge.So do some more hard math

**Watt Hours = Watts x Hours.**That takes 20 years of school. So if you rload is 3000 watts and your daily limit is 4000 wat hours gives you at most 4000 / 3000 = 1.3 hours run time a day. You are trying to run 5 to 8 hours. Your battery was dead after 19.920 wh / 3000 wh = 6.6 hours. Completely discharged beyond the point of NO RETURN. Yes you abused the crap out of your batteries.No one can fix your problem, it was broke before you ever turned it on. You got away with it during longer days of Summer and Fall with no heat demand. You pushed it over the cliff from ignorance and idiots who designed and installed the system.
