    Sudden battery problems after welding

    Hi, I have a home built camper van, which we now have been living in full time for one year. The electrical systems consists of various components, a Renogy DC/DC charger, an MPPT from Victron, an inverter from Victron and 3 x Renogy 100ah lithium batteries with self heating. It is all...

    Fuse flows for my Renogy DC-DC 40A! Why?

    Thanks, Mike! Correct, it's a circuit breaker, we just use the same word for the two in Swedish. Ok, so maybe it's a matter of poor quality. Just to be clear though, the circuit breaker breaks going from the charger to the battery – the breaker between the starter battery and the charger (60A)...

    Fuse flows for my Renogy DC-DC 40A! Why?

    Hi! I've just finished my solar installation in my van conversion and everything is working well, except for the fact that the fuse from the Renogy 40A DC-DC charger blows after a few minutes, even though it's sized according to the recommendations at 50A. The charger is connected to a positive...

    Renogy DC DC Charger w/ MPPT

    Ok, thanks a lot for explaining! The ones I've seen have been rated at 30A. I would certainly not cheap out and buy any knockoffs, so seems like it should be fine for the warmer climates I'm planning on staying in.

    Renogy DC DC Charger w/ MPPT

    Thanks for your reply! I'd be using the Renogy 100W 12V, which have the following specs: Optimum Operating Current (Imp): 5.38A Short-Circuit Current (Isc): 5.86A I assume I should be looking at the first number? Meaning 5 panels in parallel would give 26.9A? Judging from what I can find...

    Renogy DC DC Charger w/ MPPT

    I'm trying to work out how to best connect more than 400W of solar to my DCC50S. I'm probably going for five or six of Renogy's 100W panels, due to them being on offer, or something like three of the 175W. I'm having trouble understanding if I can actually use MC4 adapters or not for the...

    Advice on sizing a solar system for a van build

    I've been trying to figure out what kind of combination of solar panels I should be using for my setup, and it seems like either five or six 100W panels from Renogy would be my best option financially, instead of 3 x 175W like I mentioned in my original post. I'm having trouble working out how I...

    Advice on sizing a solar system for a van build

    Thanks a lot for your reply, Mike! That really answers my question. I think I'll stick with the DCC50S for now then and go for the 175W panels connected on buss bars.

    Advice on sizing a solar system for a van build

    Hi, So we're building van that will be used for year around living, mostly in warmer climates. I've been doing a lot of research for the solar system and landed on using the DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT from Renogy, as it seems to be an easily installed and intuitive...
