    Need recommendation 48V 3-4KW inverter/charger - no solar - just a big UPS.

    @IslandBill For a 10A sump pump backup (UPS) I did a Sungold Power LFP6048, split phase low frequency 48v 6kw hooked up to ED4LL48 server type 5kwh battery. From the subpanel that feeds the sump pump (automatically) I added a switch that can backfeed my main panel as back up power. The only...

    Seeking advice on home standby generator

    Great input to chew on from above. Some added points from my new and similar experience: 1. Was told generator should be 1.5 X inverter size, so battery and loads can be managed. I ended up about 1.2, but not worried and I can easily adjust my charger if needed for my passive home backup...

    Backup home power with EG4 LL and Schneider Electric Conext SW inverter

    Actually did a similar system, now up and running for couple of months - almost debugged. Manual whole house backup: Inverter = Sungold LF 6KW 48V Split Phase (120v/240v) (also charges battery) Battery = EG4-LL 48V 5.12 KWh Mechanical Interlock at Primary panel with backup power breaker...

    EG4-LL (V2) pre-charge resistor - how to do correct pre-charging?

    @fmeili1 Did you ever sort out your "power-on" sequence? I too have same question as I'm starting up new EG4-LL (V2) for first time, and also noticed new EG4-LL instructions don't mention like prior model. So I phoned Signature Solar tech support and was told that EG4-LL does have built-in...

    Need your advice on best dual fuel generator for 12K Sol-Ark

    @NEpowerandlight : The NG conversion is exactly what I did, purchased 2 Inverter Generators as I wanted 240V and low THD. The trick is that I'm able to connect them parallel. I'm OK with them being manual as they're for power backup, which will only be when I'm at home. I wanted 240v so I...

    UPS Backup - Basically a generator backup

    Hello @martinman. I'm also in Michigan, and like some, interested more in power backup than daily solar. I'm surprised you didn't have Sump Pump in your listed backup items. Below is my DIY approach which I think you may have a hard time finding for cheaper. I'm about 1/2 way through a DIY...

    battery instead of generator

    @SkipperJer Have you settled on a backup plan yet? I'm in process of doing something similar, wanting backup power for my worst case: basement sump pump losing power when basement if fully finished. Basically I went with budget friendlier inverter ($1100) unit which will act as a UPS for...

    Off Grid Plug N Play

    In my case I have a 1/2 hp sump pump that draws about 800w average, or 7A. Startup/peak I'm sure is a bit more. Hard thing is predicting worst of worst, which would be power outage combined with heavy rain. In Michigan we should be prepared for both, hence my endeavor. In a heavy heavy rain...

    Off Grid Plug N Play

    I spoke with Signature Solar today and they confirmed there's no problem to hook up EG4 LiFePO4 to Sungold (for charging), since I'm not doing solar. Discussed Schneider which was probably more reliable/proven, but the $$$ started adding up... for a simple pump "backup". With that I've made...

    Off Grid Plug N Play

    Hello team DIY! I need a backup power solution primarily for sump pump and secondly for home backup power. I plan for sump pump backup to be automatic, and home backup to be manual, hence split phase. My original favorite was Magnasine MS4448-PAE, but just too expensive I think for this case...

    recommened 24c DC to 240v AC

    I'm quite curious where @Skip ended up with his project? I have very similar case that I'd like basic offgrid type inverter as backup power for sump pump. - What to just hook it up primarily to AC, but if AC goes off Auto Transfer switch kicks in the DC. - With one more thing - to be able to...

    Life Power 4 battery with sungold power inverter

    5KW at 24v means a lot of DC amps I think. Others can comment better than me probably on exact calculation, but I think you're on your way to 250A DC to feed the inverter (full rate).

    Offgrid All In One 240v Output Split Phase Inverter Recommendation.

    Hello @Festus... I'm shocked (no pun) no one has yet to reply to your post, and look forward to seeing the experts weigh in! Disclaimer - I'm no expert, and have yet to install anything but can say I've spent couple years researching. Here are a few comments I can offer: > Low frequency...

    Discount codes for signature solar?

    Seems many had Signature Solar discount success earlier this year <50OFFCART> Any guess it will still work in June? Getting ready for 1st time SS purchase Eg4 & an inverter - over $3k, so 5% sound much better! Or maybe check out 2 items separately if it's $50 off only?

    Preassembled Chinese LiFePO4 48V 10kwh "Powerwall" units - thoughts?

    @Holdenmorris Thank you MUCH for sharing your unfortunate experience. Seems every good deal comes with risks. I feel lucky to have this forum! If you used your credit card and went through alibaba I wonder if there's a recourse there if they're not honoring the warranty?
