    Chargeverter efficiency is around 75%

    Sorry, weather was bad and now I am at work for a 48 hour shift and then headed to the snow to play. I dind't get a chance to test the MAgnum but I will. Quite possible I made some error in measuring. Here is how I did it. Clamp on meter at the generator. Fluke to measure voltage at the...

    Chargeverter efficiency is around 75%

    I was having an issue with a breaker popping while using the chargeverter. In the investigation process I discovered that to put 5.1kW into the batter bank using the chargeverter I was pulling 6.8kW from the generator. I was a little surprised that the efficiency was that low. That is like a...

    EG4 low V disconnect, need a low power charger?

    Thanks. That seems so bizarre. With a typical batteries, put them in parallel and the low batt will just pull power from the others. How close in voltage does it need to be? I could find nothing in the docs, do you know where I can find more information?

    EG4 low V disconnect, need a low power charger?

    Thanks for the reply FG. He has MPP solar inverters/charge controller. He has 4-5 other EG4's that are fine to run the inverter. Only 1 got down to charge protect. I don't understand why SS would tell him to buy a small (5 to 15 amp) charger. Maybe there is a reason or maybe SS is wrong again...

    EG4 low V disconnect, need a low power charger?

    Friend has an EG4 battery that went into low V protect mode. Signature says he need a small charger to bring it out of protect mode. The manual just says to charge. I don't see what the difference is between a charger and solar panels. Anyone know if you do indeed need a charger and why?

    Seems MPP dropped a new inverter...a split phase 10KW

    Having helped install two MPP off grid power systems, there is no way I would ever buy an MPP product. Both installs had multiple major issues. They are loud, run hot and love to forget settings. Even the up and down buttons don't work right on the menu. One system is still managing to run. It...

    Victron is Over-priced Eurotrash. Why would anybody buy Victron over an AiO?

    Easy. The power company wanted over 50k years ago to come out to my place. While I don't run Victron, I run quality gear and my power stays up and my chest freezer cold. Buddy of mine is in the process of getting rid of his MPP inverters and redoing his system after a couple of months of...

    Problem running a washing machine on solar?

    Glad you got one that works. Like I said I have been running the MagnaSines for many years and have never found anything that they won't run.

    Problem running a washing machine on solar?

    What inverter do you have? I have run MagnaSine inverters for years and have yet to find any device that has a problem with it. What exactly is the problem?

    High frequency verses low frequency inverters

    Low frequency inverters are heavier and more expensive to build. They are better at starting large inductive loads or dealing with multiple sure loads. High frequency is lighter and cheaper to build. This is the primary reason why they are made. For me, I have way too many inductive loads and...

    Finally ready to purchase BUT which inverter to purchase?

    Sounds like somemore homework is needed. You are being asked important questions if you want a cogent answer.

    Anyone used Expert Power?

    Thanks for the reply. I have had problems with the Docan 280aH cells. Maybe the 100aH are better but I am seeking a truly responsible battery vendor.

    Anyone used Expert Power?

    I am wondering if anyone has used Expert Power to purchase cells. I have had less than stellar experiences buying cells directly from China or from the stateside warehouse suppliers. This are the cells: https://www.expertpower.us/products/16-3-2v-100ah-lifepo4-cells?variant=40264336638050...

    Safe to Power a DC to DC charger *Directly* via Alternator?

    Well, it depends on the alternator. I think if the alternator has residual magnetism it will start producing without a battery. In which case a cap would be fine to smooth out the power. If you have a brand new alt, spin it and see if it puts out.
