    Victron shunt suggestion

    Here is an idea I hope Victron will read and implement. We need a new feature on a shunt. We need a shunt that can OUTPUT a voltage based on a state of charge. The problem is that most auto generator start systems don’t work with Lithium batteries. It’s not that a Lithium battery can’t...

    Largest ah that fits

    My RV has batteries in the step area. It would be difficult to move them to a compartment, so I would like to keep the batteries there. My step well is 26 x 8 x 11 (length x width x height). The largest battery I have found is a Lossigy 200ah that will fit. The problem I am running into is...

    Victron Tail current setting

    When my RV battery switches are on and I have the fridge on I run about 3a draw. This is the minimum draw I would see during camping. I noticed the default for Tail current was 2a. So it would seem the Victron 100/30 would never leave Absorb based on Tail current. It would stay in Absorb...

    Help with charge profile GC2 on Victron

    I have 2 6v Interstate GC2 batteries in series in my Rv. Interstate shows the following charge profile. Interstate GC2 Bulk = 14.8 Absorb = 14.8 Float = 13.5 Equalize = 16.2 They state that for every 1 degree below 77 degree F to add .0028v per cell for temperature compensation. I just got my...

    Amazon scam

    So I ordered 4 - 100 watt HQST solar panels off Amazon on Black Friday. The listing said they were in stock and available to ship. I still have not received a shipping date so I contacted Amazon today. First they told me my local distribution center did not have them and they would have to be...

    Design problem?

    Was reviewing Wills wiring and wondering if there is a problem. If the Inverter shorts out it should blow the main fuse to the battery. However the problem may be that the SCC would still be providing power to the Inverter. Likely the circuit breaker would not trip since it’s rated higher...

    What are issues charging LiFePO4 with Magnum Mm1212?

    My RV has a Magnum MM1212 inverter/charger with MM-RC remote. Magnum says it does not have a specific LiFePO4 profile. The current charge profile is set for AGM2 (because that is the profile loaded in the remote and is non changeable) that has Bulk @14.5v and Float at 13.5v. What issues would...

    How to test Magnum temp sensor?

    I have a Magnum MM1212 inverter/charger. The manual says it’s supposed to charge in Bulk to 14.6v and then switch to Absorb and hold that voltage for 120 minutes (based on my 210ah battery back size). I have the battery temp sensor connected and it will lower voltage based on battery...

    24v battery but 12v use

    Will, how about a video exploring the following: Setup a 24v battery (2x 12v batteries in series) being charged by a 24v solar charger. Obvious benefit is cheaper controller since you can push 2x the watts. However connect the inverter to just one of the batteries (12v). What would this do...
