SYSTEM DESIGN
Load Restrictions
Determining which loads the inverter will support is tricky. Having a good understanding of the system owner’s load usage is
key in configuring the load correctly. If the load is not configured correctly, it will constantly trip the inverter and produce an
overload error. The system will display an overload error when:
The continuous power required by the load exceeds the inverter specifications. When the grid is present, the continuous load
cannot exceed 7kW. When grid absent, the continuous load cannot exceed 5.5kW.
To ensure the load does not exceed the inverter’s continuous, analyze the system owner’s list of essential loads. Note which
hours each load will be running and make sure the total power used per hour does not exceed the inverter limits (7kW with
grid, 5.5kW without grid). Below is an example power usage during a 24-hour period.
Note: Loads should be configured in a way that the system owner can easily limit their load to 5.5kW when there are utility outages.
Equipment with large inrush current cause power surges that exceeds the inverter specifications. When the grid is present,
the inverter can accept power surges up to 7.5kW for 30 seconds. When the grid is absent, the inverter can accept power
surges up to 7.5kW, 6.5kW and 5.5kW for 1, 5 and 40 seconds, respectively.
It is important to know the inrush current of major appliances and equipment. Equipment with motors, such as water pumps,
will have a large inrush upon startup. Soft start devices should be installed to limit the power surges of any equipment with
large inrush currents.
Parallel Operation
Up to 3 H5001 can be connected in parallel. Each H5001 has its own charging
capability and can be controlled to work together, so you can incrementally add
power and storage in parallel at the same time. This makes designing and
configuring sites with larger demands easier.
Note
: The installation of a parallel versus a single inverter system is different. To install a
parallel system, refer to the H5001 Parallel Installation Guide.
