Re: Best Solar Charge Controller? And Series vs Parallel Wi

E350,
Don't get to carried away, you should be able to get the current draw info using the victron. For every one of those current Ammeters that you installed you would be using 5.5 watts of power...

Re: Best Solar Charge Controller? And Series vs Parallel Wi

Tare loss refers to the efficiency of the controller, while it would be true that you would use more power in a MPPT system, the extra power it gets from the panel in most cases make up for it. So...

Re: Best Solar Charge Controller? And Series vs Parallel Wi

AM refers to Air Mass. The standard test condition STC requires a Air Mass of 1.5. STC should be the same across all panel vendors. These are the values they test the panels at to get specification...

Re: Best Solar Charge Controller? And Series vs Parallel Wi
