  • Post in thread: jehugarcia Samsung SDI ESS Mega - what to do with these batteries?

    Sorry my reply isn't timely! I've got the Outback Radian inverter/charger, 8kW (good for 100% overload for a little bit!) Our 4,000 square foot house in a moderate climate has been hanging off these for 3.5 years now, Paul
  • Post in thread: Using a generator to charge backup battery?

    It seems like you could use an MPPT charge controller, and feed it a full-wave rectified output from a generator... maybe some capacitive, inductive filtering. Sure, the charge controller has functionality you don't need... but it gives you a readily available back door into the battery. I've...

    Translation: Hello, does anyone have a user manual and settings for the BMS, there are some entries that cannot be translated into English
  • Post in thread: Using a generator to charge backup battery?

    I do not see an exact solution there… My generator is 240/120 and my battery is 65 V DC. That's a tall order for off-the-shelf battery chargers, but of course a standard configuration for an MPPT. The only rub is that even a half wave rectifier on center tapped 240 will generate 170 VDC, so...
  • Post in thread: DIY ac/dc coupling mess

    What are you spendings $4k on? 4kW of Radian inverter is closer to half that... even less used.
  • Post in thread: Battero Tech BT280 3.2V 280Ah LiFePO4 Cells - US$55.00 _ GobelPower.com

    You could find, or make, a bushing to contact the larger base... maybe with a spring washer to ensure contact. Paul
  • Post in thread: Can I use my Manual Transfer Switch Home Backup Setup for Solar Backup as well?

    We installed an Outback radian inverter, fed by batteries. The outback is smart enough to feed through utility power when it's available... you could configure it to run off solar when available, then switch seamlessly to utility when the solar fades. We have an interlocked breaker setup like...
  • Post in thread: Best gas generator for a backup battery charging?

    avgas will last a very long time without Stabi. There was a military aircraft that landed on the Greenland ice cap in the 1940's. It was rediscovered and removed for restoration about 1990. The avgas in the tanks was still good, albeit in cold storage. we run avgas in our generator, shredder...
  • Post in thread: Possible To Off-Grid In Condominium Without Touching Common Electrical/Meter Room in California?

    These guys sell a system that switches solar to each unit in turn, and keeps track... https://www.electrictrees.com/et/ You don't want to sell back, the IOU will eat your lunch. On the other hand, solar can't compete with the EV rate... so let the IOU charge the car, and build solar for...
  • Post in thread: Easiest solution to provide generator "boost" for HVAC peak inrush

    If you're truly a hacker, you could add a $300 inverter to your existing compressor...you'd need to work the controls to do a very soft start... but you can get the inrush down to almost nothing. When the thermostat calls for cool, take 30 seconds to ramp that baby up to 60 Hz. If you want to...
  • Post in thread: Ecoflow not the whole home solution I thought...

    I've got an Outback Radian inverter charger, configured to never output to grid. My Reliance manual transfer switch is always in inverter mode... normal operation, the Radian passes utility power through to the house. If the utility falters, the Radian picks up in a split second: lights don't...
  • Post in thread: AGM Battery never used but 6 years old, are they still good?

    Here's a battery restoration saga, based on Concorde's published procedure. I see the pun!
  • Post in thread: jehugarcia Samsung SDI ESS Mega - what to do with these batteries?

    Hello Davis Jo, I have four of these running my house, I'd love to have four more. Let's arrange pickup! see attached for my email address.., Paul
