What is the peak current output for the cllena dc 8v-40v to 13.8v 20a automatic buck boost? will it run up to 25 amps, non-continuous?

The amps seem pretty weak on these, I installed them on my RV to convert 48v lithiums (58v actual input) and they struggle to drive the two 35 amp jacks, and I have 4 of these in parallel. Volts are low to, 58v in, 11.5-12.2 out max.

What is the amp draw on the line side of the inverter

This is a 360 watt converter and the specs say that it is up to 95 percent efficient; so, 360 divided by a nominal 48 volts DC divided by .95 is 7.9 Amps DC. Assuming a close to worst case scenario, using a low battery voltage of 42 volts DC and 92% efficiency; it could draw 9.3 amps. For sizing a fuse, 9.3 times 1.25 is 11.6 Amps DC. In summary, if you assume a 10 amp draw and use a 15 amp fuse on the line side of this converter, you should be safe using those numbers.

What is the parasitic (open circuit output) power draw of the 48->24V 60 amp model?

I have four of these connected in parallel and it doesn’t even register 1 watt parasitic draw between all of them. I cant measure anything less than a watt so I would imagine a single one of these would be in the very very low milliamperes parasitic draw

Can i use this converter to power a standard 110v wall outlet?

This is a dc-dc converter. It can't take any AC input.

works perfectly for my application

I am using Milwaukee 18M batteries to power a 12V telescope in the middle of nowhere. This device works perfectly to reduce the 18V battery to 13.8V which is perfect for my 12V telescope.
