Amperage question:
All things being equal (12V system, 100w PV, Direct Sun, etc.)
does the Solar Charge Controller 100/50 actually output more Amperage than the 100/30 under the same conditions
OR
Does it have the capability to do so, but will require more PV wattage to achieve 50A max output?
Power = Volts X Amps.
Klim8skeptic point is correct.
12v x 50A = 600W. If you install only 300W you will not see 50A of charging. Only 25A.
12v x 30A = 360W. If you install 600W here you will still only see battery voltage x amps max.
ok, thanks...to achieve the max rated Amp output for ANY of the controllers, one must connect the max Wattage of PV listed in each controller's specs...any input Wattage less than max will result in lower than max amperage output.
Does anyone "over panel" knowing that perfect conditions rarely happen and that Victron documentations shows: "1a) If more PV power is connected, the controller will limit input power." ?
Suggestion
If you adding extra panels to compensate for less than favourable conditions you are likely to exceed the max wattage of the MPPT for a given set of panels/voltage. Use multiple MPPTs in parallel. using smart solar you can charge sync them or use GX device increase solar yield.
