Re: your comment...
I've been using the Meanwell NPP-750-48 on my 48V lead acid bank since December. I use it every day for a few hours and it just works...
Any issues with your setup? What size generator? I have a 2000w Yamaha inverter generator and I'm looking at either the Meanwell NPB-750 or NPB-1200 and looking for some real world experience/knowldege.
