    What future problems are you implying? Everything is working flawlessly so far and we just got back from a 2.5 week road trip without shore power. I'm not sure why I would throw a grand at that Victron unit when I already have an inverter and 80 amps worth of charging ability. I just need an...

    Yeah that's why I got an oversized 3500 watt inverter to run a 1400 watt air conditioner. It starts up fine even when running the microwave, not that I ever use the microwave, but I guess if I wanted to it wouldn't be an issue. Nothing else really runs on 120v in my RV. The water pump is 12v...

    The two EG4 chargers I'm using are 40 amps each and 29.2v (.4c charge rate) and I'm not planning to stop using those. So my batteries see 29.2v regularly, regardless of my solar system settings...so I'm still confused why solar charging should be any different from non-solar charging. Power is...

    My battery bank is 200ah 24v, so the rovers combined would be a charge rate of .3c right?

    And as far as that balancer goes, I looked at this same unit a while ago but never bought it . Is it definitely worth using one? How important is balancing with two 12v in series? Obviously they both have their own internal BMS's and the manufacturer doesn't push using a balancer. But I...

    Actually what I would really like is a 24v charger with adjustable output so I can dial it down, for example if I was at high altitude generators puts out considerably less power. Hmm

    TL;DR I need a lifepo4 24v20ah charger! Hi! I'm new to the forum but happy to be here! I recently built the following system in my 27ft camper: Battery: Two 200amp hour 12v lifepo4 Redodo batteries wired in series for 24v/200ah. Chargers: Two EG4 24v/40ah chargers (80ah total) that I got from...

    Thanks for the reply, but I am a little confused by the recommended user settings. My battery manufacturer recommends a charge voltage of 29.2v and the AC chargers I use are already charging at 29.2v, so why would I want to solar charge at a lower voltage? Wouldn't this decrease the speed at...

    I think there's a misunderstanding here between charging voltage and battery full charge voltage. My battery, like almost all lifepo4's, is considered full at 13.6v (27.2 for the pair in series). My charger charges at 29.2v (14.6v per battery), but once they are full, it stops and the surface...
