Title: Solar panel. Charge controller
Post by: Randy Keaveny on April 20, 2026, 10:23:17 PM

98. Beaver motor coach.   Thinking my original charge controller. Or. Controllers are not working as my newer batts keep on dyeing.  Not charging.  Who knows the size if the original panels ??  And charge controllers.  I plan on replacing the one under the rear bed.  Engine compartment.  Not sure where the other one is located. 

Thx for any help. 

Randy.

On mine the one under the bed was the only one and it also died.  Almost any MPPT charger you can find will be better than the original in my estimation.  I replaced mine with a victron unit and also ran new wires through the fridge vent to the inside.  I also replaced the Solar panels with 2 100 watt panels in the same footprint.

Thanks so much for the info.   I dont know that much about solar.   so am learning on the fly.  we purchased remote property here in Sitka AK.  and are going solar   so im learning as we go.  then it dawned on me. that the solar on my motorhome is the same. only in a sunnier place. lol.  and my batts keep on draining.  even the new ones.    not blaming the charge controller.  but. thats where I am starting.   

ill have to follow those wires from the top.  down thru the engine room.  but pretty sure they go right into the batt compartment which holds starting and. house batts


thanks for the info
