Default solar panels

Our solar panels arrived today, 2 80 watt panels, Morningstar Sunsaver 10, wire and mounting brackets. Now to start the installation. The Sunsaver 10 is PWM so won't be as effective as a MPPT controller. That was the trade off to keep the system price below $500.

Default solar panels first test

Tacked everything together to make sure the system is functional. With 21 volts into the controller and 14.8 volts out indicated a good charge even with a low angle of sun light on the panels. This was done at 3:30 pm EST. The estimator program from AZ wind and sun indicated 12.77 amps into the battery. At present I can't measure above 5 amps DC and I realy have doubts about the spread sheets estimate. The volt drops were correct but the current seems high like maybe their controller estimate is for mppt not pwm.
I'll have a better idea once installation is complete.

You might have to wait awhile. His last post in this thread was 10+ years ago, and he hasn't logged on in about a year and a half.
