    DC to DC charging toggle switch?

    Thanks a bunch.

    Ecoflow Delta2 max DC output question

    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...

    DC to DC charging toggle switch?

    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...

    BougeRV CIGS - Any Reviews?

    IDK. Boxes are not marked made in China.

    Why not CIGS?

    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...

    Use RV inverter as generator for house

    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...

    Just got Ecoflow Delta PRO, can I use external LiFePO4 batteries to add capacity??

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

    Use RV inverter as generator for house

    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...

    Grounding roof mounted system - confused

    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...

    Home Rooftop PV Cable Routing

    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...

    Just got Ecoflow Delta PRO, can I use external LiFePO4 batteries to add capacity??

    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...

    Why not CIGS?

    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...

    Why not CIGS?

    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...

    BougeRV CIGS - Any Reviews?

    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...

    Just got Ecoflow Delta PRO, can I use external LiFePO4 batteries to add capacity??

    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...
