    looking for a quiet or no fan inverter for 24 or 48v. any recommendations?

    I'm building a tiny house for a remote location. it's incredibly quiet and peaceful there and I couldn't stand to listen to inverter fans all day and night. who has experience with a 24 or 48v inverter, 2-3kw, that has quiet or no fan noise? right now I'm in an off grid cabin and it uses a 12v...

    Renogy 48V 3500W SOLAR INVERTER CHARGER

    anyone have updates on this unit? I am considering it - mostly because I may be installing the batteries and inverter/charger in a dedicated bunker/shed to keep the batteries from freezing in a cold climate cabin and to isolate the fan noise from the unit, but would want easy remote monitoring...

    Any well pump experts? I had a thought...

    if it were me, I'd put in a storage tank and a small pressure tank using a much smaller pump. HF and other places sell small pump/pressure tank combo units for $150 or so. motor rated at 10 amps, so a way smaller battery setup to power it! not to mention, the startup surge would be way less...

    troubleshooting trimetric meter inaccuracy

    I might just go that route, I agree with you, I haven't always been impressed with the trimetric. to boot, It's located in a building that is a vacation rental and it would be nice to monitor the batteries without having to intrude.

    looking for pump advice for cabin water system

    Having lived off grid with a number of different types of systems, I prefer to have a good supply of water - at pressure - that doesn’t require power to use. It’s worth it to me to spend a bit of extra money and work to get that peace of mind. and in a climate where a couple days without water...

    troubleshooting trimetric meter inaccuracy

    I read through Rod's article. it's excellent, though I was already familiar with most of that, he goes into good and clear detail. all that still just makes me more confusted, though. almost everything he talks about is really about what causes ah counters to display a higher SOC than the...

    looking for pump advice for cabin water system

    Ideally aiming for 70-80 ft above the cabin for decent pressure there. Cabin is about 20 ft above the well head.

    troubleshooting trimetric meter inaccuracy

    it was set closer to that before, for the AGM bank, and the discrepancy seemed worse. am I wrong in understanding that the efficiency factor discounts the charge amperage to account for the charging inefficiency of lead acid batteries, and that the lower the efficiency factor number, the less ah...

    looking for pump advice for cabin water system

    Hi, I am planning a power and water system for an off grid cabin. have about $5k to spend on everything (pump, pipe, wiring, battery bank, CC, inverter, BMS) and want to use the funds wisely. so, the plan is to pump water from the well (80 ft) which is located in a winter-shaded spot, up to a...

    troubleshooting trimetric meter inaccuracy

    I'm not sure if this is the best forum for this question, but here it is - last fall I upgraded an aging AGM bank on my off grid property with a bank of LFP prismatic cells. nearly the same total capacity (~28kwh @ 24v) but of course the LFP allows much greater discharge. overall it's been a...

    EVE-280 cells should these be clamped tight or spaced for expansion?

    I just want to chime in here... I just recently built a 24v bank out of 80ah eve cells for a solar storage project. 15p8s. I used 1" boards on the ends of each parallel string with heavy duty 6" screws into 2x2's along the top and bottom to clamp them. I attempted to clamp them to the point that...
