I have an D2M which I use primarily for ac loads, but also as dc backup for an LFP battery. Unfortunately the D2M 12v output is limited to 10 amps through its 12v outlet. However 10 amps should be enough to run all your dc loads (10amps x 12volts = 120watts. If your dc loads exceed 120w...

That sound like a grest approach. Each panel is 40 Voc, so I must use both PV ports to support them. Can I connect two sets of cables to the external battery? Both of them wired to the PV ports? I don’t think I need mc4 connection, as you can buy XT60i to ring terminal harness on Amazon. I...

That’s pretty much what I want to do because I don’t want to route through roof and walls. PVC conduit would keep out water and critters. in my case, I think I can tuck the conduit into a gable corner where it’s out of sight as much as possible. I’m thinking of punching through to basement...

IDK. Boxes are not marked made in China.

I’ve got three BougeRV 100w CIGS on my camper in parallel to my Victron 100/30 mppt controller. BougeRv gave me the first one to do a review which I posted on two other forums. I liked the CIGS so much that I bought two more of them. All are double-sided tape prepped (no grommets) I tested on...

I love CIGS! They perform way better than mono in real world camping situations. See my other post. I tested CIGS against mono. The panels cost more, but the array actually costs less than hard mono panels, when you add the cost of mounting hardware, plus paying somebody to install them...

The glue down corner mounts might work well on a fiberglass roof, but I definitely wouldn’t trust them a rubber type roof any more than rails with VHB tape. When air gets under the panel while driving, there will be uplift force. That force can rip the rubber sheath off the substrate. Most...

Do you need an inline fuse on the XT60i harness?“

Yah agreed, if you don’t mind extension cords running all over your house. I suppose that’s tolerable for a one day outage, but running the basement furnace is another matter. I dunno, I’m lazy. New setup allows me to just go flip a couple of switches to keep our house running for a day with...

You’re probably right that hard mono has the advantage if you’re doing a DIY install. But there’s so much risk in putting holes in your roof unless you REALLY know what you’re doing. I would never buy a used RV with a DIY hard mono install. There are tech shops that you have to pay some heady...

Thanks for your informative reply. I have another issue. I’m routing PV into basement mounted circuit breakers and then into my Ecoflow delta 2 max, which has two charge controller inputs, both rated at 60v/15amps. There fore I need to run two sets of cable in order to maximize pv input to my...

I would like to charge my 2kWh powerstation, and a 3kWh LFP from the same 12v 50 amp Victron dc/dc charger. But not charge both simultaneously. To switch the charge between batteries, can I wire the dc/dc positive lead to an a/b/off disconnect switch, and negative from the switch to grounded...

Thanks a bunch.

I’m doing a small 1Kw backup/off-grid roof install. I’m kinda lame, but I don’t see any advantage to grounding the pv. I’m routing each panel through a 30 amp pv breaker. We live in the mountains where we get a lot of electrical storms. Our OTA antennae was a lightning rod, so I took it down...

Hello, New to the Forum. I installed roof and portable solar systems on my RV, and put in a hybrid inverter/charger and 2Kw LiFePo4 house battery. Recently acquired an Ecoflow Delta 2 Max 2Kw powerstation to supplement capacity in our RV, but primarily to serve as the cornerstone of a home...

I’m putting a couple of 340w Qcells on my roof as a start for a small off-grid system. I need To terminate pv cable connections in my basement, but I don’t want to do a rooftop entry. Has anyone routed their cables through conduit from the roof, down exterior of house and into their basement?

I’m thinking of adding an external 12v 200ah to my new Delta 2 Max. 200ah LFP so cheap now. I’m gonna charge the EF through it’s 12v car charging port. It’s only 8 amps max, but that’s a charge of about 100w. Slow, but good enough to supplement solar and transfer the entire external capacity...

Easiest is single phase to a 15 amp generator receptacle on the house. Just completed this install. From inlet on house, ran 12/2 romex to an outlet I installed near mains. i connect my powerstation ac charge cord to this outlet. I can then feed this circuit with a small generator, or an...
