3.3.4.2 EPS Connection
HYT-HV series has On-grid and Off-grid function, the inverter will deliver output power through the GRID
port when the grid is on, and it will deliver output power through the EPS port when the grid is off.
A standard PV installation typically consists of connecting the inverter to both panels and batteries.
When the system is not connected to the batteries, the manufacturer strongly advises that the backup
function not be used. The manufacturer will not honor the standard warranty and will not be liable for any
consequences arising from users not following this instruction.
• If you need to connect Diesel Generator (GEN) Connector, please contact
Hoymiles for more information.
NOTICE
WARNING
Before connecting, please make sure all requirements listed below are followed.
• Use the Grid Connector from the accessory box. Damage to the device
due to the use of an incompatible connector shall not be covered by the
warranty.
• An independent three or four-pole circuit breaker must be installed on the
output side of the inverter to ensure safe disconnection from the grid.
• Multiple inverters cannot share one circuit breaker.
• Never connect a load between the inverter and the circuit breaker
• Make sure the EPS load power rating is within the EPS output rating,
otherwise the inverter will shut down with an “overload” warning.
