I have a fully off-grid 48v system and I'm looking to upgrade the inverter.
My main purpose is charging an EV and while I don't care how fast the car charges, I am trying to maximize the electricity that actually gets into the car's battery because my system is panel constrained.
My current setup works but is bottlenecked by my Victron Phoenix 48/1200 which can't even max out L1 EV charging (1440 watts). I have to set the car to charge at 10amps @120v which means my charge efficiency is pretty low because enabling the car's charge circuits draws a decent share of the current.
Ideally I'd like to get to something that can support a minimum constant output of 2,880 watts at 240v which seems to be a good minimum for optimizing efficiency into the car's battery.
It looks like sticking with Victron would mean I'd have to get two inverters to create 240v. Even the cheapest MultiPlus 2kVA at $940 should work for my needs but doesn't leave much room to upgrade in the future.
And two multipluses is $500 more than the EG4 6000XP at $1,450 which comes with 240v out of the box.
I realize the eg4 has a high frequency inverter vs. the LF in the victron and victron has a better reputation, but it's tough to pay more, have to buy more wiring, find locations for mounting screws etc. for the same capabilities.
Any recommendations one way or the other? Or is there anything else I'm overlooking?
Here's what I'm currently eyeing.
$940 - Victron 48V MultiPlus 2kVA Inverter – 25A Charger
$1450 - EG4 6000XP Off-Grid All-in-One Inverter/Charger
And if I go Victron, is there a super compelling case to go for the UL listed one with a little more headroom?
$1275 - Victron 48V MultiPlus-II UL1741 3kVA 120V Inverter 35A Charger
Thanks in advance!
