GHESS 9.8-14.4-TH hybrid system
Note: maximum charging current, maximum discharging current, discharging stop voltage and
charging stop voltage should be set before commissioning to maintain battery’s lifetime. These
parameters are set in LED screen.
5.2 System Starting
1. Turn on the DC switch (optional) on the Powervortex 309KTL
2. Turn on AC breaker, connect to the grid
3. The inverter is ready to work, wait until the system status of LED display shows “Normal” success
4. Turn on the switch on the battery pack and press the red button "SW" until the power light is on,

5.3 System Operating Instructions
5.3.1 On-grid Operation
The hybrid inverter has 2 options of operation mode:
1. Self-use Mode
If there is enough sunshine, PV energy supplies the load first and then charges battery packs; if
the load power is covered and battery is full charged, surplus energy will be fed into the public
grid to acquire the FIT
If there is no sufficient PV energy, the system discharges the battery pack first; if PV power and
battery discharging power is smaller than the load power, then the grid co-supply energy to the
load
