EG4 6000XP Truck Camping and backup Home Solar Generator

Trying to figure out if it is OK to use a EG4 6000XP for intermittent truck camping around 300-400 miles drive to camp sites (thinking 4-6 times a year). Want to build a dual purpose portable Solar Generator that works with my house system most of the time, but be able to take it off-site for the occasional camping trip.

Planning to build a dolly Solar Generator with the EG4 6000XP + (2) 48V EG4 batteries, both to
1. feed my Sol-Ark 15k grid-tied system at home as a 'Generator' tie on regular days, and
2. take it off-site on my truck for intermittent camping trips so I have AC power to run my 120V refrigerator and gears at the camp site.


I will be installing one of my left-over 540W 48v PV panel on top of my truck canopy, and connecting it to the proposed Solar Generator (EG4 6000XP+48V batteries) at camp sites or on drives. This way I can also hook up system to a campsite power supply if there's no sun to charge the batteries. Don't want to spend more hard-earned cash an elusive 48V refrigerator as most systems are 12/24V.

I already have extra batteries and PV panels that are 48V, thus my thought on putting an EG4 6000XP. I am quite similar with the Sol-Ark, so hopefully less learning curve as opposed to going with a Victron. Lastly, since I have EG4LL batteries, may as well stick to the same ecosystem for the inverter.

Any feedback will be greatly appreciated. Thanks.

You must feed the 6000XP mppt with AT LEAST 120Vmp for MPPT operation. It won't even start unless it sees 100Voc.

"48V" - do you mean nominal or 48Voc? If 48Voc, that's actually a "24V" panel.

If 24V, for single panel operation, you'd need a separate boost MPPT connecting the panel to the battery bank. The Eco-worthy at 12A output might be the best option.

The plan is good, if you get enough solar connected to it.

Good advice! I forgot about the minimum voltage for MPPT to even start.

My panels are JA Solar 540W Bi-facials https://www.jasolar.com/uploadfile/2021/0706/20210706053456650.pdf .

Still hoping to be able to dual use an inverter for home and the rare camping trips. Maybe I can add the Boost Charger to separately charge the battery via the truck PV. The Inverter can still be used to provide 120V outlets and also charge the battery at a campsite hookup. Think that will work?

As long as you can achieve at least 120V for the MPPT to operate, you're all set. However, keep in mind that shading can affect performance, so it's best to aim for a voltage higher than 120V to ensure reliable operation.

Using an EG4 6000XP as a dual-purpose solar generator for both home use and truck camping is a great idea. I recently installed a off grid home backup system at home .Mine is this https://rocksolar.ca/collections/off-grid-solar-systems-for-homes-cottages
