Solar fuseing, confuseing
Were installing a Renogy 400 watt solar system on our fith wheel. We stay on our property about two months in the summer up near Canada in Washington.Anyway this is the kit I bought. Mind you I'm comp...

Here it all is. Except an Rv is not a stick house, and you don't have to worry about firemen on your roof
EDIT--
"optimum conditions can provide 30% more current to the battery under charge. I have measured such on my own system in central Oregon coast and seen such results. PS: there is no such thing as a MPPT controller having PWM mode"
What an absolute crock! EG an MPPT only does MPPT in its Bulk Stage but does PWM during its Absorption and Float Stages.
Your MPPT controller provides amps to battery from its output watts divided by the battery voltage. So if output watts is 200w, then amps to the battery is :
12.5v is 200/12.5 = 16.0 amps
13.5v is 200/13.3 = 14.8 amps
14.5v is 200/13.8 = 13.8 amps
So if you are selling MPPT controllers of course you will only mention how good they are against a battery voltage of 12v!
Meanwhile, if you actually have any solar, your morning voltage will be in the high 12s already so the fabled MPPT "advantage" is never seen. BTDT--have you ????? :(
Getting so tired of this BS, sorry. :(
