Qualified person
If there are several inverters and only one battery in the system, the battery should be connected to the inverter that is to be configured as the System Manager.
Bridge at GSI terminal must be inserted when operating with BYD battery
Upon delivery of the Sunny Boy Smart Energy, there is a jumper wire on the GSI terminal block. This jumper wire must be removed when a switch for the fast stop is connected. As soon as the jumper wire has been removed, operation with a battery from BYD is no longer possible.
Requirements:
The battery power cables must be pre-assembled.
Procedure:
- Disconnect the inverter from all voltage sources ( > Check that the inverter is de-energized).
- Insert the M25x1.5 cable gland with two-hole cable support sleeve into the enclosure opening for connecting the battery power cables and tighten it from the inside with the counter nut.
- Unscrew the union nut from the cable gland and lead the cable through.
- Remove the two-hole cable support sleeve from the cable gland.
- Insert the battery power cables into the enclosure openings. In doing so, pierce the closed side of the enclosure opening.
- Press the two-hole cable support sleeve including the battery power cables into the cable gland.
- Route the battery power cables to the terminal block BAT+ and BAT-.
- Connect the battery power cables to the terminal block BAT+ and BAT- according to the label. To do so, insert a flathead screwdriver into the top opening of the terminal and insert the cable into the bottom opening. Then remove the screwdriver.
- Tug lightly to ensure that the cables are secured in the terminals.
- Tighten the union nut on the cable gland hand-tight.
