    Off-Grid Geothermal Heat Pump - SOLVED!

    We have an off-grid setup with a single Sol-Ark 15K and 8x 100aH batteries. My geothermal system was rebooting the inverter due to the amperage being pulled at startup (154 amp LRA). My HVAC vendor sucked and was no help. I researched and found the EasyStart. Not convinced, I ordered it...

    Voltage Drop

    My Sense Labs is showing more voltage drops than I'd like. Have a Sol-Ark 15K, 40kWh EG4 LFP batteries, and 10.92kW in solar. Is this an issue with how my electrical panel is set up since it's leg two that's too far out of spec? Is this going to ruin sensitive electronics/appliances? ICF home...

    Sol-Ark 15K + Generator

    Generator experience / advice, please. Much appreciated!!! I want to go with a propane standby generator and have it start up when my batteries hit X%. The Sol-Ark is already set up for that, but it just runs outside to a 30A / 220V plug that I plug in to my Predator 9500 when my batteries get...

    Water Battery Idea

    I recently read about Switzerland's new "water battery" (https://electrek.co/2022/08/02/check-out-this-massive-swiss-water-battery-that-can-power-up-to-900k-homes/) and had an idea. I want to do a fish pond on my 12 acres. I was thinking about doing two ponds, one at the top of our hill and one...

    Clear Solar Panels

    I'm looking at doing a roughly 1,000 SF greenhouse on my property. I've read some articles about clear solar panels and I'd like to use them for the roof of it. I've not been able to find a vendor to supply me with them though. Has anyone found a vendor that has them, or a similar technology?

    Clothes Dryer

    I have a clothes dryer that uses about 3500 watts in "medium" heat mode (what I typically use). When I start it it makes the lights flicker, barely noticeable. 1) Is this going to hurt any sensitive electronics or any part of my inverter/battery system? 2) Is there a way to prevent it from...
