Turn off solar panels???
I have a new solar install that is working great, but I have a question. I have 3 - 280 watt panels feeding thru an Outback combiner box (each panel on it's own breaker) and then into a Morningstar Tristar MPPT-60 charge controller. The battery bank is 4 - Trojan T105 RE'S for 450 ah's at 12 volts. I can run the battery bank down to 70% at night and on a sunny day, the panels have the bank back to 100% by 10:00am plus running a few other loads. So far, looks like I have plenty of panel vs batteries and everything is working as designed.
Now the question. This is a small, off grid cabin. I use it for 5-7 days once a month, then it sits unused for 3 weeks. Should I shut down the solar panels while I'm gone (or turn off the breakers to two of the three panels) or just leave everything at full power and let the charge controller handle everything? Or, should I leave a few smaller loads on and let the inverter power them to use some of the battery capacity daily. Now, I turn off the inverter and throw the disconnect from the batteries to the inverter. Is it acceptable to flip the circuit breakers off when the panels are under load? Thanks for your answers!
