Note:
•BAT cable must be tightly crimped into the
connectors
•There will be a click sound if connectors are inset
correctly into BAT plugs
Note:
•Please use BAT plugs and connectors in
GoodWe accessory box
•BAT cable should be standard, 4-6mm

：
For the compatible lithium batteries (Pylon/BYD) connection, please refer to battery connection
part in BT quick installation instructions.
Prepare BAT cables and BAT plugs
(Figure 2.4.1-2)
Battery wiring connection steps as below:
Screw the cap on and plug onto inverter side (Figure 2.4.1-4)
Connect BAT cables to BAT connectors
(Figure 2.4.1-3)
Note:
•There will be a click
sound if connectors
are inset correctly
into BAT plugs.

•Use the right BAT plugs in the accessory box.
•Use the tin-plated cables with a conductor cross section of 4 to 6 mm² (AWG 10) because the
maximum battery current is 25A. Battery cable requirements are as (Figure 2.4.1-1).
Make sure battery switch is off and battery nominal voltage meet BT series’ specification before
connecting battery to inverter and make sure inverter is totally isolated from AC power.
[4]
Please following requirements and step bellow strictly. Use improper wire may cause bad
contact and high impedance, which is dangerous to the system.
•Please be careful against any electric shock or chemical hazard.
•Make sure there is an external DC breaker (
≥
40A) connected for battery without build-in DC
breaker.
The inverter is suitable for mounting on concrete or other non-combustible surface only.
• Please use the mounting bracket as a template to drill
4 holes on right positions. (10mm in diameter, and
80mm in depth) (Figure 2.3.2-1)
• Use expansion bolts in accessory box and fix the
mounting bracket onto the wall tightly.
Note: Bearing capacity of the wall must be higher than
25kG, otherwise may not be able to keep inverter
from dropping.
Carry the inverter by holding the heating sink
on two sides and Place the inverter on the
mounting bracket. (Figure 2.3.2-2)
Note: Make sure the heat sink on inverter is
right joint with mounting bracket.
Ground cable shall be connected to
ground plate on grid side (Figure
2.3.2-3)
A lock could be used for anti-theft if it is
necessary for individual requirement.
