Battery Bank How Big?

by Josh
(Az)

Question: I got 6 panels 4 120 watts and 2 125 watts panels putting out 730 watts at 42 amps @ 12 volts. How large of a bank should I go with to get the most out of my system. Looking at the sunxtender batteries over lifeline batteries since my main input is off the solar system and not the converter. Also it is all mounted on a 1989 pace arrow. Thanks for all you help!




Robbie: Wow 6 panels is a large system I hope you did your homework and are using a regulator capable of running 6 panels. To answer your question on how many batteries I think you can use as many as you have the room for. It really depends on how much invert time you plan on using. If your not inverting very much you have no need for a large bank of batteries. You have plenty of power from the panels to run 6 batteries no problem. Make sure you keep the terminals clean and the system serviced as one bad connection can cause a lot of trouble.

Thanks for the Question Good Luck,
Robbie
