Important — Battery Voltage Requirement
- The battery voltage connected to this inverter should always be above 500 V
- Maximum discharge current is 100 A — if battery voltage drops below 500 V, the inverter will limit output (e.g. 430 V x 100 A = 43 kW)
- If loads exceed the limited output, the inverter will produce overload errors
- Select a battery configuration that maintains voltage above 500 V at all times
System Compatibility
- High-voltage battery system — refer to the Sunsynk HV Battery Compatibility List for confirmed compatible batteries
- When deployed with Freedom Won batteries, log a ticket with Freedom Won to update the battery profile for Sunsynk 50kW HV compatibility
- Up to 10 units in parallel, each with its own battery stack
- Can operate without batteries (PV and grid only)
Installation Notes
- At 75 kg, mechanical lifting equipment or a multi-person team is required
- IP65 rated for indoor or outdoor installation
- Installer must be a qualified three-phase electrician with product-specific training
- Specific manufacturers may require training prior to installation for warranty conditions
- Non-compliance with installer requirements will lead to warranty invalidation
Certifications and Compliance
Warranty
- Standard warranty: 5 years
- Extended warranty: 10 years when paired with Sunsynk batteries
Common Questions
Click a question below to reveal the answer.
Why must battery voltage stay above 500V?
The inverter's maximum discharge current is 100 A. If battery voltage drops below 500 V, the maximum power output is limited (voltage x current). For example, at 430 V the inverter can only deliver 43 kW. Loads above this limit will cause overload errors. Select a battery configuration that maintains voltage above 500 V at all times to achieve the full 50 kW output.
Can the Sunsynk 50kW operate without batteries?
Yes. The inverter can operate using PV and grid power without batteries connected.
How many Sunsynk 50kW inverters can be installed in parallel?
Up to 10 units in parallel, each with its own battery stack, for a maximum combined output of 500 kW.
What training is required for installation?
The installer must be a qualified three-phase electrician with product-specific training. Some battery manufacturers may also require their own training for warranty compliance. Non-compliance may invalidate the warranty.
