It works as advertised 
I have a few clients with generators that are too small to run their inverters so I use the chargeverter. 

Yes paralleling them is no different than paralleling charge controllers

As to 120 or 240v input the same cable works just put a different plug on the end. Obviously it won’t do as many amps at 120v.

Picking up a dormant subject, has anyone used the EG4 Chargeverter yet? Impressions? They are shipping now from one of my distributors.

I'm also wondering if they could be paralleled onto the battery for double the amps, I see no reason why not. That would be cheaper than buying a 10kw inverter/charger to use as a dumb battery charger only.

My application is to use them with a totally manual start/stop genny for emergency charge. Open loop with existing inverter.

FYI, there are some portable-looking 48v 50-100A chargers in the range of $600-$800 online, no doubt Chinese, but if you're only using it a few times a year....

Jason,

The NOCO GX4820 is a great charger. I've used it to dark-start Fortress and Blue Planet 48v cabinets, instead of dinky trickle chargers taking hours to do the same job.
Priced at $500 a year and a half ago. its rated @ 110 -240 vac input. The one I bought came only with a 120v cord.

I'm looking for a suggestion for a good all-around charger for service purposes. I would consider a 240V or 120V option. The purpose is primarily to charge 5kWh lithium batteries.

I would probably just pick up an EG4 Chargeverter, but it is back-ordered. Something more portable would be nice.
