    Project Update for Victron MultiplusII and 840 watt solar panel install.

    I have been busy past few days. The positive leads from the solar panels go into a breaker switch then into the respective SCCs. All wires from the roof to the SCCs are the same length by color. All the black negative lines from the roof to SCCs and from SCCs to Bus Bars are equal. The positive...

    Are DC to DC chargers really necessary.

    I am installing 2 310 AMP nominal 12 volt batteries in parallel to my 5th wheel. I am also installing 840 watts of solar panels hooked 2s then each pair running to its own EPEVER 40 Amp SCC. Given my 5th wheel is parked and charging a lot more than it is running down the batteries I am...

    300 Amp Shunt

    The last piece of my puzzle is the Shunt and Battery monitor. Other than the Brand Name is there a really good reason to go with a Victron vs an approximately half priced shunt and monitor?

    Finally Arrived Victron Multiplus II

    The victon Multiplus II I ordered the end of May came yesterday. Time to measure roof order panels and rest of stuff to go solar. Have the Battery Cells for 2 310 AH LiFePO4 batteries on hand and the BMSs for them

    Pre Charge Circuit for solar controllers and Inverters

    I am considering wiring in a pre-charge circuit for my solar controllers using a 100 watt 30 Ohm resister a switch and probably 10 guage wire to essentially bypass the main breakers to the SCCs and a separate bypass with another resistor for the inverter. The goal is to pre-charge capacitors...

    By Pass Multi Plus II pros and cons

    Planning on installing a new victron multiplus II 3000 12 volt. Is it a good idea to wire this in with a by pass or just run the shore power directly to the Multi plus II directly then bring the AC back to the distribution panel? Think a couple of those 1-0-2 switches would get the job done...

    2 310 AH 12 Volt LI FEPO4 batteries 4s each with own 150 Amp BMS and 2 210 Watt 2s Solar Panels and 40 AMP charge controller

    I am planning to make 2 310 Amp hour batteries each with 4 s configuration and its own 4s 150AMP BMS and connected to a 40 amp Solar charge controller. My question is how to hoop up the solar charge controller. Part of me wants to just hook the negative lead from each SCC to the load side of...

    Best way to get Solar Wires from roof to Basement in Elkridge E292 5th Wheel?

    Still in the planning phase of this project that will eventually end with 4 210 Watt Solar Panels connected 2s each pair connected to its own 40 Amp controller connected to 2 12 Volt DYI Lithium 310 AH batteries and most likely a victron multi 3000 12 to 120 inverter converter. I am rather at a...

    How to configure Batteries Solar Panels BMS and SCCs

    I had initially planned to configure system with 280 AH Cells in a 2p4S configuration and run my panels 2s 2P into A single 60 AMP SCC brand immaterial for now. Having read a lot of posts on the forum a lot of folks are running 4s2p configurations using 2 BMS one for each 4 pack. Having read a...

    Is a Shunt necessary if I have a 300 amp BMS smart bms with blue tooth built in to my self built 560 AMP 2p4s lithium battery

    essentially the title says it all. If there are real advantages of say using a victron shunt in addition please enlighten me

    Researching and going to build an RV Solar system.

    I am researching putting a solar system on my Elkridge Extreme Light E282 Fifth Wheel. Planning on building my lithium battery 12 v 280 or 270 ah cells with 4s 2p configuration. with a 250 or 300 amp daly bms. Will be putting in a 3000 inverter onto the system. I may possibly use the...

    Yet another Newbie

    Been dragging a 5th wheel around for about 10 years now and really dont want to run a generator all the time or stay with full hookups. I am looking to build a solar system for my Elkridge E 292 Extreme lite Fifth wheel. Probably running 2 laptops 3 to 4 hrs making 2 pots of coffee just brew...
