Special Adjustable Settings
The inverter has field 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 to
allow inverter work under on-grid condition
(Figure 2.4.3-1). For details, please check the
official application plan on website -GoodWe
Hybrid Solution For Split Grid Type.
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.
• 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.
• 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.
Note：If you don't use the back-up function or use on-grid power to charge the battery,the wiring
conduct core section can use 4-6mm

Note：Make sure the terminal cover is rightly
locked onto the terminal.

Back-Up wiring connection process is as below:
An external AC switch (≥32A) is needed for Back-Up connection to be isolated when necessary.
Note: The absence of AC breaker on Back-Up side will lead to inverter damage if only electricall short-circuit
happend on Back-Up side. And Back-Up function cannot turn off under on-grid condition.
