User Manual V1.3-2021-12-15 02 Installation Instructions
Note: The absence of AC breaker on Back-Up side will lead to inverter damage if only electrical short-
circuit happened on Back-Up side. And Back-Up function cannot turn o under On-Grid condition.
An external AC breaker (≥32A) is needed for Back-Up connection to be isolate when necessary.
1. Prepare the terminals and AC cables.
2. Put AC cable through terminal cover and screw
the three cables tightly on the connectors.
NOTE:
I. Please use the terminals in GoodWe components box;
2 Make sure cable jacket is not locked with conductor. Torque 0.7~0.9N.m

Lock terminal cover and screw up the
terminal cap.
Connect the assambled AC terminals
onto inverter.
Make sure terminal cover
is locked up here.
Press the button and
hold it to unlock when
unplugging AC terminals.
Note: Make sure the terminal cover is rightly
locked onto the terminal.
Note: Make sure it is connected to 'Back-Up' side
(other side connected to public grid).
Special Adjustable Setting
The inverter has led adjustable setting like tripping point, tripping time, reconnect time, active
and invalid of QU/PU curves etc. by special rmware. Please contact GoodWe after sales for the
special rmware and adjust methods.
Connection For SPLIT Grid System
In SPLIT grid system, there is a solution allowing
inverter to work under On-Grid condition. But
the export power and load power might be
detected inaccurately as the nominal output
power of inverter is 230V and there could be
loads of 110V or 220V.
Declaration For Back-Up Function
The below statement lays out GoodWe general policies governing the energy storage inverters
of the series ES, EM, SBP, ET, EH and BH.
1. For Hybrid inverters (Series ES, EM, EH and ET), the standard PV installation typically consists
of the connection of the inverter with both panels and batteries. In case of systems not
connected to the batteries, the Back-Up function is strongly not advised to use. GoodWe shall
not cover the standard warranty and be liable for any consequences arising from users not
following this instruction.
2. Under normal circumstances, the Back-Up switching time is less than 10 ms (the minimal
condition to be considered as the UPS level). However, some external factors may cause the
system to fail on Back-Up mode. As such, we recommend the users to be aware of conditions
and follow the instructions as below:
1) Do not connect loads if they are dependent on a stable energy supply for a reliable operation
