RV SOLAR INSTALL COMPLETE - VICTRON - USING ALTERNATIVE BATTERY SYSTEM

Finish completion of my solar system. It has 3000 W of solar panels on the roof and all Victron components. Also using Samsung brand new old stock batteries purchase from batteryhookup.com that I had to disassemble and a put in a different configuration so I was able to use them in this application..

I have a full crate with the same Samsung SDI batteries Ive been trying to sell for the longest because I couldn't find any use for it. Now watching this video it gave me a purpose. Thanks!

They've worked good for me.

Thank you for sharing. Beautiful RV!

I have life po4 different types. Ltos as well and honestly those being some of my favorite ones

[@omarsegura2847]

Life po4 are heavy for RVs

[@omarsegura2847]

Nice set up! Those are good battery cells. Samsung sdi prismatic 4.2v 72ah. Lighter than life po4 cells. With those victron no need for bms but it’s safer!! Beautiful Rv!! I have those batteries as well

[@5StarPWC]

Yeah - I think you’re right I didn’t need them BMS’s but it was my first system so I’m learning. I purchased one of battery hook ups DC charges and I can set it to take these batteries up to the exact amount I want. You say these are 72 AH - 4.2 cells?

[@omarsegura2847]

My mistake, they are 68ah and that’s 4.2 fully charged. Resting voltage at 3.7 v per cell

[@billygoldberg140]

Dude! You need to line those solar panels up! Put at least 4 in series. Check the Maximum PV voltage IN on your Victron Controllers,and try to get it up there. ( but don’t go over ). With such fine equipment you should be running 150 volts,but by all means- read the owners manual. Mine says minimum 90 volts,and the inverter does not even come on until it hits that.

[@5StarPWC]

thanks for the recommendation

[@roadrescue829]

Just curious did you get your voltage up? I have a 16s lithium ion battery running at 65v on my victron system this sounded like you had the battery set for a lifepo4 battery charging my multiplus ii charges up to 64v and my victron 150/70 mppt takes it to 65v on solar I did buy the programming cable for victron that lets you get into charging parameters

[@5StarPWC]

65v is basically maxed right? added a charger i picked up, I did a video on it, following this one. I would like to change the charging parameters myself, what's the cable all about?

[@roadrescue829]

@5StarPWC And yes 65v is max system voltage for victron 48v multiplus ii

[@andrewr05]

You're definitely missing out on a lot of capacity not being able to charge them up to their full voltage. How did the new charger work that you got? Were you you able to get a full 3 days out of them afterwards?

[@5StarPWC]

I added a charger that takes them up to 64.3 v check the next video
