Testing and setting inverters without batteries

[golfwisconsin]

I recently purchased two 48V 3,000W Victron Multiplus 2 inverters from a gentleman who claimed they had never been used. After inspecting the components inside, I’m inclined to believe him—they look brand new.

At the moment, I don’t have any 48V batteries available, but I’d like to test the inverters and set them up for dual-phase operation so they’ll be ready to install when the batteries arrive.

I do, however, have a 48V battery charger, and I was wondering: has anyone ever used a battery charger to power on and configure Victron inverters instead of an actual battery? If so:

Were there any issues with the charger maintaining stable voltage and current?

Did it allow the inverters to power on fully for setup?

Any tips or precautions I should take to avoid damage?


I’d appreciate any insights, advice, or experiences you can share. Thank
s in advance!

Most new battery chargers will only work if they detect a battery (of the necessary voltage range). Probably best to wait until you have a proper battery to use.

Use a power supply. Just an idea, not sure if it will work.

I would get a battery before trying to program the units with out a good stable power source could be problematic a cheap 50 Ah only runs around $350

My Quattro can be powered up by energizing AC-In-1. For some reason, it wouldn't initialize from the battery but would once AC-in-1 had power.
