thanks @OffGridInTheCity !

I'm trying to understand the efficiency of inverters. I'm planning on getting the Victron Multiplus 12v 3000w inverter/charger because I'll have 600+ AH of LifePo4 batteries and because it can charge the house battery bank faster than the 2000w inverter/charger. However, (with the exception...

Thanks @x98myers7 @Rocketman and @73powerstroke I'll have 600w of solar on roof, and while I could potentially put additional solar on the ground, I'd still like to be prepared in situations when sky is cloudy for an extended period and I'm relying almost entirely on my battery system for 6-7...

I'm planning my electrical system for a van. I'm not running high wattage appliances and I'll only be using about 1-3kwh per day, but I'll often be away from grid for 6+ days and my solar won't be enough to fully recharge batteries. Ultimately I need to have ~14kwh of capacity. Here are two...

Thanks for all the additional information everyone. To answer your question @rickst29 I'm open to alternatives like 24v or 48v if they'll work better for my needs. I'm still figuring how all of this works and all the different options. I estimate I'll be using about 2-3kwh per day, but...

Thanks so much @sunshine_eggo @rmaddy and @Samsonite801 !!! So if I understand correctly, if instead of shore power I have a gas generator that outputs 2000w at 120v it would be: 2000W/12V * .85 efficiency = 141A So the generator would charge the batteries at the same speed as the shore power...

I'm confused how 30a at 120v from shore power gets translated through an inverter/charger into a 12v battery bank. For example, if I have six 206ah SOK 12v batteries wired in parallel and I'm charging from 30a shore power via a Victron Multiplus inverter/charger, how much will each battery be...

I've heard that it's best to get batteries all at the same time, since mixing newer batteries with older batteries is less efficient. Is that true for the AC200max as well? For example, if I were to get the AC200max, use it for a year, and then add a B300, and then add another B300 a year after...
