Of course, If you get audited by IRS, then you need to show...
  • Post in thread: 110v internet based power switching?

    I got one of these to control my 9000 BTU 110v Pioneer mini-split remotely. For whatever reason (maybe because my room is too small) the thermostat on my mini-split wasn't controlling the temperature and my room was ending up 65 degrees when the thermostat is set to 74. Now this unit turns off...
  • Post in thread: EG4-Lifepower4 Short Circuit Protection

Under this situation (and being off grid), the inverter circuit boards (including its FET drivers) are not...

    Bluetti EB3A was not designed correctly and the company should stop selling it. I have noticed in the UPS mode, when the battery level drops below 100% and the EB3A starts to recharge its battery, during that period of time, the unit generates too much harmonics on the 120-volt AC line that...
  • Post in thread: EG4 6500EX 48V Back Feeding to the Grid

    The EG4 6500EX-48 is considered an off-grid inverter and it functions as a load (like your toaster) when connected to the grid, and it is not possible to back feed to the utility. When grid power is lost, your inverter could get its input power from the solar panels or batteries (for feeding its...
  • Post in thread: How to set up exhaust fan in greenhouse... on a budget

    A few solar panels and a small inverter feeding a thermostatically controlled exhaust fan would do the job (similar concept as an attic fan) but it may not be cost & time effective, if you have access to grid power, unless you just like to experiment and learn.

PS. it appears that the output of your little gas generator is...

    I would first look for any load that could possibly deplete 30,000 watts in less than six hours (six batteries) or 5000 watts every hour. If my mini-split HVAC was on continuously, it would have consumed 1000 watts, so in 30 hours (a little more than a day), it would have depleted all the six...

  • Post in thread: How many watts of solar panels?

Therefore, if your panels are generating half the watts (i.e., only getting about...
