from Titisville, Florida asked:
October 5, 2017
Recently survived Hurricane Irma. Lost power for 48 hours, but it could have been much worse. Will this unit power my entire home (including fridge, freezer, oven, central A/C, TV) when the power goes off? Does it automatically switch on when the grid goes down (any delay times)?
1 Answer
This unit will not power your entire home but it will work to power energy star fridges, freezers, fans, lights, TV, computer, laptops, cell phones, etc. We do not recommend any solar units for A/C since they draw a lot of power. This system can be tied into a back up sub panel by an electrician which can power certain designated circuits. The automatic power transfer would be dependent on the transfer switch chosen and installed by your electrician.

from Syracuse,In asked:
August 24, 2017
How long does it take to put a full charge into the aforementioned generator unit? Can additional 330 watt solar panels be added for a more robust capability?
1 Answer
It takes anywhere from 5 to 8 hours to fully recharge using the included solar input. The solar input capacity is at its maximum allowance with the included 2640 watts of solar and therefore cannot be increased. Thank you for your inquiry!
