    SolarEdge (SE7600A-US) Inverter and custom battery pack?

    Approved batteries are only Tesla and LG. There is a "battery control" interface in addition to the +/- connections. So that is why I was wondering if ANYBODY else out there has tried it. Would be nice to hear from someone else's experience.

    SolarEdge (SE7600A-US) Inverter and custom battery pack?

    Asked last year if anyone out there has tried using the SolarEdge StorEdge Inverter and was able to couple it with a custom DIY Powerwall pack. Do not know if anyone has successfully done this. It is approved to use with Tesla and LG lithium Ion batteries. Not sure what would happen if one tried...

    Batrium Low End Voltage & Questions

    Do I need a shunt for every bank, or will one suffice, or do I need one at all?

    Batrium Low End Voltage & Questions

    Knowing what I know now, probably would have only charged that pack up to 4 volts. BMS is top balancing it down to the level of the others. This was the first time I had a way of charging on my bench (kitchen counter top). Pretty happy with my DIY converted pc power supply and DPS5020 unit built...

    Batrium Low End Voltage & Questions

    Thanks, makes sense. Set my AC support on inverter to charge with grid power when pack goes below 45 volts. Charged one pack on bench all night set at 4.2 v 10 amps, and pack was up from 3.86 v to 4.13 v, so stopped charging. Worked great. Going to put it back into service, and pull out...

    Batrium Low End Voltage & Questions

    This may have been covered elsewhere, but how low of a voltage is it safe for your battery pack to get before you allow it to recharge? My setup is 14s100p, charged from daylight to dusk with PCM60X mppt solar charger. Have a Schneider Conext SW4048 Inverter that can be used on or off grid...

    PCM60X setup and MPPTracker software

    Got MPP Tracker installed, up and running. Only way to connect is via the serial data cable. Had to run Ethernet cable through attic to drop down into my computer room. Would be a lot better if there was a way to get it to work via wifi. Anyway, have both the MPPTracker and Batrium BMS...

    Batrium Toolkit for Android Tablet?

    Replaced my 3.79 volt pack, found a lot of bad cells. New pack started at 4.11, and still doing well. Found also that the solder connections on the negative busbar came off super easy. Have been roughing up the busbar with a file before soldering for some time now, and this appears to have...

    PCM60X setup and MPPTracker software

    Up late getting the Schneider unit configured. Electrician left the AC backup connection breaker off by mistake, otherwise may not have shutdown, but at least I have some idea of what I can power, and for about how long. Found the CD from MPP Solar, now to get it transferred to a jump drive so...

    PCM60X setup and MPPTracker software

    Just finished first night powering a portion of my house with my Powerwall 14s100p. Ran out of "juice" at 5:55 am, awakened by the beeping alarm from the UPS connected to my computers in the room next to my bedroom. Ran a lot of lights, computers, microware oven off and on. Still trying to get...

    May have been answered somewhere else, but is it possible to install the Batrium toolkit software and monitor remotely from and Android cell phone or tablet?

    Batrium BMS Questions

    Perfect. Ordered box and DPS unit from Bang Good. Will get the ATX power supply modded while waiting for goods to arrive. Thanks for your help.

    Batrium BMS Questions

    So if we have 5 volt and 12 volt outputs (assuming they are DC) on computer ATX power supplies, that would be more than enough to supply power to energize the DPS5020 unit and charge a single 100p pack of 18650s on the bench? If so, I have several functional ATX power supplies, 300-600 watt...

    Batrium Interfacing With Chargers

    Sounds like will be much better. Anyway, mine is working now. Watched your video on the DPS5020 build. Ready to order the box and kit to build, but am still unclear how to power this unit from 120volt AC house current. Can you use an ATX Power Supply from an old computer to supply power? Or...

    Batrium Interfacing With Chargers

    Disassembled the plug from both sides, was able to get the molex connector pins ALL the way in, then reassembled front and back, and finally got the shunt to work. Hope the new shunt they are using will be a bit easier. This one is being discontinued.
