    EG4 18Kpv Documentation

    Last year when I was looking into AIO systems I settled on the EG4 18Kpv. I remember seeing documentation on the signature solar site that went through all the different installation methods possible with this inverter. I can't find this PDF now and I didn't download it. Do any of you know...

    EG4 18kpv Questions

    I'm really liking what I see with the EG4 18KPV but I have a few questions. I'm in the middle of an energy audit now and I have a baseline of around 900-1000w of continuous usage before items like HVAC and other appliances factor in. I'm using about 30-40 Kw a day. This will probably go up for...

    Gathering Data Phase

    I'm in the middle of a geothermal installation at our home and I've been given the green light from my SO to do a residential solar installation since our camper setup is so successful. This is in Wisconsin, USA I've installed Emporia Vue2 on my main circuit breaker to get a good understanding...

    You’re never too old to install the entire system by hand.

    Because of this video I've decided I'm just going to make a "shed" and then mount my panels on the shed. Our inspectors are pretty easygoing here but my town is growing quickly and it's bound to get harder to get permits for projects like this.

    CATL to mass produce 500 Wh/kg batteries this year

    "Needed" depends on the application. For mobile applications, space and weight are at a premium and the higher the energy storage density, the better.

    CATL to mass produce 500 Wh/kg batteries this year

    CATL says they're going into mass production this year, so they will be available. The only question in my mind is, how much of a premium will I have to pay for them?

    CATL to mass produce 500 Wh/kg batteries this year

    CATL has announced plans to manufacture batteries with almost twice the capacity of the batteries used by Tesla. This will enable the electrification of aircraft. While this isn't as energy dense as the lithium air batteries which have been developed and achieve 4 times the energy density of...

    Three panels, three controllers, one battery. Optimum panel placement?

    One thing I was worried about with that is a controller not pushing in enough current because of higher voltage created by other controllers. I have already run into a situation where a smart charger(AC) wasn't bulk charging when it should because of the voltage coming in from the solar...

    Three panels, three controllers, one battery. Optimum panel placement?

    At our off grid cabin in Canada we have 2 100 AH AGM batteries. They are currently separate, running separate circuits. Because of uneven loads and the solar panel situation I plan to put them in parallel and have all loads on the same circuit. This runs led lights, cell phone chargers, marine...

    Help dealing with voltage drop

    I'm having trouble finding the right diodes. The highest rated amperage I've seen is one amp and I know there could be up to 20 amps going through the line when it's under load.

    Help dealing with voltage drop

    But since I am already running across 50 feet of 12 gauge from the house battery I should be getting a voltage drop to begin with. So no need for a diode, right?

    Help dealing with voltage drop

    I should have mentioned that the pump is triggered by a drop in water pressure. So it's remotely switched. I don't know anything about series diodes, I'll have to look into that. Thanks!

    Help dealing with voltage drop

    Is it as simple as wiring up the pump battery to the house battery? Are there any issues if the house battery is AGM and the pump is a smaller FLA?

    Help dealing with voltage drop

    It's coming from a 12V AGM battery that runs lights and radio in the house. 48V source isn't an option.
