You'll be much happier with the BattleBorn batteries and if you haven't already purchased them I'd suggest contacting AltE in Boxboro for great products, support, and pricing. Don't forget to change the Depth of Discharge in your inverter from the 50% lead acid setting it is likely at now to 80%.
I have been enjoying a similar 12 volt based system on my pondside cabin for three years now and though limited in output it has served me well by running a refrigerator, fairly strong stereo, all the lights that I'll ever want, and brew that essential pot of coffee in the morning.
For the longest life you will want to bring your batteries home for the winter and keep them where it is warm and charge them once or twice.
Finally, and assuming the your roof array is pointing to a perfect solar south (194 degrees and a 35' pitch) you might be able to get a little more solar gain by canting some or all of modules to more to a more southeast orientation to pick up your charge a bit earlier in the morning |
We actually go up every weekend year round, so the batteries stay there connected.
The shed roof is pointed south, and the roof panels are parallel to the pitch of the roof (12/12 pitch)
The 3 160 watt wall panels are on the east end of the shed, so they catch the early morning sun.
I already purchased the Battleborns from Continuous Resources, I have bought most of my components from them, Great support, good prices, and free shipping on most things. On the 6 Battleborns, I saved over $900 compared to the price from AltE. They are supposed to be delivered tomorrow.
The Trojan set up is in the shed, for ventilation purposes. The Battleborns will be set up in the basement of the cabin since they don't need to be vented, and they do need to be kept warm.
