Im looking at expanding my Apex 300 solution using the A1 hub for whole home backup. Im currently using a small inverter generator to charge my Apex during power outages. In my future plan, I will setup a sub-panel with my essential circuits and connect it to my Apex bank using the A1, which will connect back to my main feed to power when the batteries and sub-panel when power is normal.
My question comes in as this, how do I charge the Apex bank using my generator during a power outage? Will I need to upsize my generator to have the head room to charge the batteries AND float the load to the sub-panel? Where in the setup does my generator input plug live? Thanks in advance for any help!
Thank you for your inquiry! Here are the instructions for charging the Apex battery pack with a generator:
When there’s a power outage, how can I charge the Apex battery pack using a generator?
Connect to the charging port using the AC charging cable. If the generator’s power is insufficient, please adjust the maximum input current on Hub A1 according to the generator’s maximum output current to avoid overloading the generator.
When there is AC power input and the unit is in standard UPS mode:
If the generator’s power exceeds the load power, it will prioritize bypassing the load, with the remaining power charging the battery. Otherwise, both the generator and the APEX300 battery will output power to supply the load.
