Can 370 Watt Solar Panel Replace 165 Watt with 25 Amp Controller
Updated 02/03/2026 | Published 07/30/2024
Question:
I have a 2021 Grand Design Transcend Explor, or as other Grand Design owners call it, the Entry Level Trailer.. Came with the Furrion 165w solar panel and 25amp solar controller. Can I replace the 165 with the 370 and keep the 25amp solar controller.. I have 3 only have 2 hooked up at the present time Weise AGM sealed 100 amp batteries, and Bluetti 2000 watt solar generator with 350 watt portable panels, just for the heck of it.. Thanks in advance for the answer...

Expert Reply:
You have more than enough amperage left on your controller to upgrade to a higher rated panel to put a bigger charge on the system. We don't carry a 370 watt roof mounted panel otherwise I'd recommend one.
