Normal capacity?

Muvtan

I only get 3,7 out of the promissed 4,6 kwh on the LiFePo version. Addon batterie is still incoming...Normal?

Depends on how you measured that. Did you consider inverter losses?

Muvtan

So yes. I used the EU 240v 50hz ac output. But 80% efficiency would not be that great?! Maybe for a mobile battery...

80% efficiency is about right. Your true efficiency depends on your load. With the SBV, it has a fairly large 3kW inverter, so maximum efficiency is probably somewhere between 1kW-2kW. If you have a smaller load for a longer time, your efficiency will be lowered.

In an ideal world, we could use more DC powered devices to avoid the inverter power loss, but of course most devices are designed to be plugged into a 120VAC

Muvtan

Aaaahhhh yes. Ok that makes sense. My typical load would be between 350 and 900w. Roger. I was just wondering if something was wrong maybe. Got it! Thank you!

Muvtan

Yes but it would be a lot more dangerous for the enduser.
