What to check
How to read the comparison and pick the right model
- 1
1-phase or 3-phase supply
Match the model to your supply (see your power bill or meter). A 1-phase model can't run a whole 3-phase system.
- 2
Battery or not, and which voltage
On-grid has no battery; hybrid and off-grid do. Check the Battery row for 48 V or high-voltage (HV) to match the battery you'll use.
- 3
How many panels
Max PV input and the number of MPPTs tell you how many watts of panels fit and how many roof directions.
- 4
Backup in a power cut
If you need power in a cut, check backup output, switching time and surge (air conditioners, pumps).
- 5
Where it goes, and warranty
Outdoors needs IP65 or better; IP20/IP21 models go indoors. Then compare the warranty.
