Wondering if anyone with GoPower flexible 100 W panels have had to replace them after 2 years. Second query, has anyone upgraded AGM's for lithium. If you have would you descibe what's involved. Thanks, 2021 Wonder RL
2021 WRTB, 400 watts flexible, no issues or visible degradation to date. But I live in Alberta and don't spend much time in high heat conditions. I upgraded to lithium last season with a single 200Ah self heating unit from Ionic here in Canada. Straight drop in, no changes or upgrades needed. everything is working just fine. There are other battery options out there and prices are a moving target so some research is probably needed for your application. Be very aware of your size requirements. Many of these batteries are assembled with non standard case sizes and can vary from brand to brand.
What year & model?
Upgrading depends on what you have now.
I had 400watts of flexible which were starting to look grayish, after 3 years. I had the room so installed six 100watt solid panels, this also needed a larger solar controller.
Thanks for replies!
I just got done replacing my (2)100Ah AGM's for (2) 300Ah Epoch LiFePO4 batteries. Pretty straight forward to do, just make sure you;
Turn off the inverter, disconnect the main house power switch & protect (cover) the Positive terminal connection while working in the bay as there is still power coming from your solar panels.
Here's some pictures of my replacement. I wanted to reuse the battery trays to keep things from moving around. However, my new batteries where a bit wider and longer. So, I cut the trays in quarters so I could get the new batteries into them and remounted them in the bay. Worked out well.... reduce, reuse! Also, really like the Epoch bluetooth monitoring app!
