2022 cougar with solar

[judieb68]

Hi all. I have 2022 cougar 316rls. 2 200 watt solar panels, 30A victron smart controller.
Downloaded app to monitor. 2 12v lead acid batteries.I have no idea what settings are supposed to be or what the readings mean. Anyone with knowledge, your help would greatly appreciated.

Here is the quickstart guide for the Solarflex 400i from the keystone site. It has the configuration settings. If not the right system, you can find more information on the solarflex tab.

This is what my victron smart charger is showing me on a perfectly sunny day. Doesn't look right to me. Battery amps should be
30 shouldn't they?

60 watts at 38.35 VDC is 1.5645371577 amps. (60/38.35=1.56) Your readout of 1.6 amps is a "rounded up to tenths" accurate for the solar output.

The battery charge condition, 13.69 VDC at 4.2 amps is 57.498 watts.

You can't get 30 amps of output power from a 4.2 amp input power. It's the same 60 watts "converted at a different voltage" but the same "effective power".

Given that there is some power used in converting the solar panel voltage (nearly 40 volts) to a usable 13.7 volts to charge the battery, the 2.5 watts energy loss makes up that difference...

Unless your solar panel array is producing 30 amps at the battery voltage, you won't read 30 amps on the status panel. That would be, hypothetically, 38.35 volts and 1150.5 watts (38.35x30=1150.5). Then you'd get "sort of close to 30 amps at the battery input" (minus the energy loss to convert the power.
