Off-Grid Upgrade Minimal Design – Victron Multiplus-II and 900AH Epoch LiFePO4

[jd1923]

Not that we need this much power, but a new Victron Energy MultiPlus-II 12/4k/160-50 120V just came out for $1,105 (no tax or shipping cost with this vendor). It's at a good price, having paid $997 for the 3K model July of 2024. Also, very good customer service with InvertersRUs. They serviced a warranty replacement for me on a small Victron MPPT SC. All I had to do was to email the pic of the Victron Connect app screen. They shipped a new one out immediately with return label.

It provides 4KVA (3.4 KW) inverted power and can charge up to 160A. It's 2" longer, the same width and 3/4" taller, plus 7 LBS heavier than the 3K model that several of us have installed, so it will just fit in the streetside basement.

With a whole lot of LiFePO4 Ahs, you could use this kind of power, if you're still running an ol' school single-speed compressor A/C and don't want to worry about what else you power up! No Soft/Easy Start needed with this bad-boy and you won't ever get stuck with a Multiplus failing for low voltage cutout. With required input as low as 9.5V your batteries may cutout before the MP2 ever will!

Wow, checking my thread above on page 1, it was two years ago to the day, when I finished my installation. We are rarely plugged in and never turn it off, so our MP2 has run 24x7 for a full 2 years now, always providing service without issue. 😎

Nice, though I'll probably stick with the 3k model for size and weight. I know it's not too much, but I don't think I'll ever need that much power in my rig. 

BTW, it won't be long now before I'll be adding solar and lithium- so be ready to get your brain picked! 😂

The 3K model is enough, especially with your efficient Turbro inverter A/C (or your new Chill). I hope you bought one of the open box/used MP2s at half price! With the 4K model out, look for deals on the 3K models coming soon! 

I just looked again at the picture of your beautiful hull #45! Remove that king antenna and mount solar panels sideways. I'll bet today you can get near 800W up there! Install two drive motors so you can pitch the panels up on both left or righthand sides! Would be so cool. Consider my brain picked (just for now)! 😎

Haven't bought anything yet, just still in the beginning of the planning stage. And that King antenna was removed within days of buying #45... Ended up bringing it to @mossemiwho also lives here in Tampa. 

Have to get my son off to college and complete the move to our new place in Floral City Fl, but once that's done, upgrades will be priority #1!
