    Remotely switching from BMV 712

    i have an abundance of solar in my caravan and have normally fully recharged my batteries by mid morning. What I want to do is To install a heated towel rail and use the 712 relay to switch it on at 90% SoC and off at say 85%. This will normally allow my towels to dry out during the day...

    Keeping LIFEPO4 at 70%SoC

    I run a 24V 200ah system for my travel trailer. My MPPT is a Victron 35A. I have 1kw of solar and run a compressor fridge constantly. I have set the absorption voltage to 27V and float to 25.8 and find that the system settles at about 70% SoC after a few days. A day before I head...

    Counter Intuitive Winter Solar Output

    I have made a very interesting discovery which I think I can explain. My RV has 1000W of solar panels flat mounted on the roof. It is now the middle of Winter here in New Zealand with about 10 hours of daylight and quite low sun elevations (30 degrees and zenith). My RV is parked in the...

    Replacing DC-DC Charger with an inverter

    My Caravan system comprises of 1000W of solar, 200 a/h of Lifepo4 at 24v and a Victron Multiplus 3000 240v. I go through about 2Kw/hr a day and have had no issues so far replenishing this with solar even in dodgy weather, however as winter comes on this will increase. I do not use DC DC charging...

    Shallow Depth of Discharge, LIFEPO4

    Hi, I am running a compressor fridge off 1000 w of panel and only lose about 7% SoC overnight. (14a/h @ 24v). Am I better off cycling between 93% and 100% every day, or set it up with a lower rebulk and float voltage so it cycles every 4th day between 70% and 100. In summary are fewer...
