  • Post in thread: LG leaving the Solar Panel market this year.

    i sent an email to them about whether we could buy remaining solar panels at a discount. haven't heard back yet.
  • Post in thread: Backup Power Solution (All In One?)

    thanks for the correction. i did figure the charger for 10 amps because i don't yet know what the charger puts out yet. just got it yesterday in the mail. will hook it up today for a test. the specs. say 10 to 15 amps. i haven't checked the actual battery capacity either. 10 amps would be...

  • Post in thread: sodium-ion batteries .....

    https://natron.energy/wp-content/uploads/natron_collateral_BR500_092822-1.pdf look at this pdf at the end of page 3, start of 4. with this module all the cells are wired in series and the best system use is for 500 volts out. look at how easy it would be to re-wire the ten cells in parallel for...
  • Post in thread: Best path for increasing battery bank capacity

    my math correct? you pull in 2260w x 5?hours = 11300wh during the day. how many watts does it take to run the minisplit? multiply that times 24 hours. if the mini takes more than you produce; then you need more solar panels, put a timer on your mini, or have your neighbor turn on the mini...
  • Post in thread: eel battery just out...like bluetti and ecoflow, stackable to 15

    the back of the solar panels usually has the specs. on it.
  • Post in thread: Need inverter recommendations for offgrid house

    the victron quattro is almost twice the cost, but i really like it because it will charge my batteries when on the grid, two grid inputs of 100a each, and at the same time it would run my kitchen power lines. i will check out cerbo, but i think multiplus is out of the question because most of...
  • Post in thread: Testing MPPT algorithm with a power supply

    i bought one to test it out, but couldn't get any info. on adjusting it. 0 to 331vdc output with 220vac input. 10 to 15 amps. really cheap and i figure it's useless, but will make a good experiment. finding a 48v battery charger to put out 30 amps is really difficult or extremely expensive...
  • Post in thread: Pics comparing freezer spec to actual current

    it might be interesting to graph the inrush current, figure the watt hours during inrush, measure the cycle time/on/off when the freezer is full, and then compare inrush watt hours to operating watt hours.
  • Post in thread: Testing MPPT algorithm with a power supply

    please show us how you did it.
  • Post in thread: Using excess solar to heat house

    how about plugging in a space heater to your inverter? i bought a couple of 350w space heaters with fans and i can use them to keep from turning on my base board heater...thus saving the power that the b.b. heater uses. most space heaters are 1500w. you could pick which heaters your system...
