Conduct Core Section 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
2) Do not connect the loads which may in total exceed the maximum Back-Up capacity
3) Try to avoid those loads which may create very high start-up current surges such as
Inverter Air-conditioner, high-power pump etc.
4) Due to the condition of battery itself, battery current might be limited by some factors
including but not limited to the temperature, weather etc.
Special Adjustable Setting
The inverter has filed adjustable setting like tripping point, tripping time, reconnect time,
active and invalid of QU/PU curves etc. by special firmware. Please contact GoodWe after
sales for the special firmware and adjust methods.
Connection For SPLIT Grid System
In SPLIT grid system, there is a solution
allowing inverter to work under On-Grid
condition (Pic 25). But the export power
and load power might be detected inaccu-
rately as the nominal output power of
inverter is 230V and there could be loads
of 110V or 220V.
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 off under On-Grid
condition.
An external AC breaker (≥32A) is needed for Back-Up connection to be isolate when
necessary.
Back-Up wiring connection process is as below

NOTE:
1. Please use the terminals in GoodWe
components box;
2. Make sure cable jacket is not locked with
conductor
Note: Make sure the terminal cover is rightly locked
onto the terminal (Pic 19)
