Advanced Solar & Battery Management
The PQ Series is designed to maximise the amount of solar energy generated, stored and used within the property. Excess solar generation can be directed into the EQ5000 battery bank for use later in the day, helping to reduce grid consumption and maximise solar self-consumption.
The system can also be configured around compatible time-of-use electricity tariffs, allowing batteries to be charged during lower-cost periods and discharged when grid electricity is more expensive.
Whole-Home Backup Capability
With an integrated 63A bypass and backup switchover of less than 4ms, the PQ Series provides a powerful platform for whole-home backup installations when designed and installed accordingly.
Smart Monitoring
FoxCloud provides remote access to system performance, including solar generation, battery state of charge, household consumption and grid import/export, allowing users to monitor and manage their energy system from their phone or web browser.
