Mainly because I want everything to go through the Renogy DC2DC charger because all my monitoring goes through that, so I can see what state the batteries are in, what is charging them, how much/long they are used/charged for, etc.
Yea. Frustrating since it's all mounted and only .5w more... it works, but when it reaches the full potential of charging, it triggers the error. I will try to step it down to see if that fixes it; if not I need to figure out a replacement or just re-route some things. Thanks for your help.
Success! The bridge rectifier was perfect. Installed according to the instructions above and I am running on solar power now. Although I did lose a volt, the DCC30 seems to be happier and charging at the highest level it has since I set this all up. Here is the install pic. The second photo is...
The title is a bit ambiguous so let me explain my situation. I have a complete system set up in a Land Rover LR3 for off-grid adventures: a starter lithium-ion battery (antigravity 80ah with jump start) and a house battery (renogy 50ah lithium ion) connected to a renogy dc2dc charger with a...
I think I follow. Do you think something like this would work (connected from the solar panel output to the DC2DC charger input) - https://www.amazon.com/gp/product/B07KWX33X5/ref=ox_sc_act_title_4?smid=AFHAE9RJVUMB&th=1
The idea would be to step down the voltage to 25v or less.
For the full system, I use this:

And then on the house battery, I use this:

Yea, I was thinking the same thing, but the entire idea of this set up is for the panel to charge both batteries... so I need to think through this a bit.
I like the sound of this, but it is WAY out of my wheelhouse. Any chance I can get more guidance on what diodes, how to wire them in, etc? It seems like a single diode will drop 0.6v-1.2v (exactly what I need!). I am just clueless on where and what to get there. I am still researching though...
