Anyone?

Mandatory connections for a BMV-712: (1) Black (negative) battery wire from the negative terminal of the battery to the "BATT" side of the shunt. This should be the only connection here. (2) Everything else to the "LOAD" side of the shunt. This got me when I connected the negative lead from...

I have some questions about a 12V battery bank on my new to me boat. It consists of four Valence U27-12XP batteries that were wired in parallel without an external BMS, but voltage-disconnect protected by a Victron Battery Protect device. I've removed the batteries for testing at home. The...

I'm going to get whatever Victron MPPT that the Victron calculator recommends and probably oversize it some. So that's going to be new as well. I guess another option would be to go with 4x the option one cells in series-parallel on the Bimini hooked to one MPPT, and two of the option two...

The one scenario in which I think this might make sense is if you split your time between cruising and RVing. In that situation you could move your Ecoflow/similar device from one vehicle to another. Otherwise, if you build your system out of components you are going to get a better quality...

The battery bank in question is 4 x ePropulsion E163 batteries @ 48V, a total capacity of 652ah. I'm considering the best way to wire a set of solar panels in series-parallel (two strings of two panels each) to maximize the charging performance. In total, the first option has a higher Voc/Vmp...

Found the answer in a owners manual I was able to download from here: https://dicksbluebirdbus.x10host.com/Valence%20XP-Power-System-User-Manual-Rev-4-8.pdf Steady red means "This indicates that the module onboard electronics is not functioning, and the processor has stopped. If a module...

Decided to go with two separate 600 watt (200 x 3s) strings each with its own MPPT. Now I just have to figure out a bus bar/breaker system to divert all the power from the two MPPT without connecting the two E163s in parallel.

I have a bank of three U27-12XP batteries wired in parallel. I'm trying to set up a Mastervolt Powercombi-12-1200-50 inverter charger's settings to work with this bank. The variables I can control are bulk charge voltage, bulk charge time, absorption charge voltage, absorption charge times...
