Q :
What is the maximum PV input voltage?
A :
The maximum PV input voltage is 1100V DC for all models.
-
Q :
How many MPPT trackers does each model have?
A :
50kW: 7 MPPTs; 63kW: 8 MPPTs; 75kW & 100kW: 10 MPPTs; Each MPPT supports 2 PV strings.
-
Q :
How do I clear an AFCI (Arc Fault) alarm?
A :
Turn off all DC and AC breakers, wait for the error to clear, check PV wiring, then restart the system. If Error 425 persists, contact Growatt support.
-
Q :
Can the inverter operate off-grid?
A :
Yes, models with UPS function (AU/HU series) support off-grid operation to power critical loads via the LOAD terminal.
-
Q :
What is the battery voltage range?
A :
The battery voltage range is 750–1000V for 3P3W systems and 820–1000V for 3P4W systems.
-
Q :
How do I set up remote monitoring?
A :
Use the ShineTools app to connect the inverter to Wi-Fi or 4G, then monitor via ShinePhone or the ShineServer website.

Q :
How many hours will 500 kWh of energy last?
A :
500 kWh is a unit of measurement for total energy. To convert this to runtime , you need to know the continuous load in kW. Use the following formula:
Runtime (hours) = 500 kWh ÷ Load (kW)
1 kW load → 500 ÷ 1 = 500 hours
5 kW load → 500 ÷ 5 = 100 hours
50 kW load → 500 ÷ 50 = 10 hours500 kilowatt-hours (kWh) is the unit of measurement for total energy. To convert this to runtime (hours), you need to know the continuous load in kilowatts (kW). Use the following formula:
Operating time (hours) = 500 kWh ÷ Load (kW)
1 kW load → 500 ÷ 1 = 500 hours
5 kW load → 500 ÷ 5 = 100 hours
50 kW load → 500 ÷ 50 = 10 hoursImportant considerations for actual systems
Power factor (apparent power vs. active power) must be considered in AC/industrial systems.
Efficiency losses (conversion, inverters, wiring) reduce actual runtime.
Peak or fluctuating loads may shorten effective runtime (compared to steady-state load assumptions).
Reserve margin: Avoid discharging to 0 kWh.Typical B2B Application Scenarios
10 kW server rack: 500 kWh provides approx. 50 hours backup time (excluding losses)
25 kW industrial motor load: Expected runtime approx. 20 hours
In PV+storage systems, 500 kWh storage supports 20 kW site load for approx. 25 hours (after efficiency losses).If you provide equipment power ratings or load curves, Sunpla will calculate precise runtime estimates—accounting for losses and reserve margins—using descriptive text, tables, and charts.
