Special Adjustable Settings
The inverter has a field where the user could set functions, such as trip points, trip time, time of
reconnection, active and invalid of QU curve and PU curve etc. by special firmware. Please
contact after-sales for the special firmware and adjustable methods.
Connection For SPLIT Grid System
In SPLIT grid system, there is a solution to allow inverter to work under on-grid condition. For
details, please check the official application plan on website -GoodWe Hybrid Solution For Split
Grid Type.

Screwing torque
2.0-2.5N.m
1. Connect the assembled AC cables into AC terminals with fastening torque about
2.0-2.5N.m.
Note: Connect back-up terminals before connecting on-grid terminals. Make sure it is not
connected to a wrong side.
2. Lock the cover and screw the cap.

Declaration For Back-Up Function
The back-up output of ES hybrid inverters have over load ability.
For details please refer to the technical parameters of ES series inverter section (Page 31).
And the inverter has self-protection derating at high ambient temperature.
The below statement lays out general policies governing the energy storage inverters of the series
EH, EM, ES, ET, BH, BT and SBP.
1. For Hybrid inverters (Series EH, EM, ES and ET), the standard PV installation typically consists of
the connection of the inverter with both panels and batteries. In the case where the system is
not connected to the batteries, the back-up function is strongly not advised for use. Manufactur-
er 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 failing on back-up mode. As such, we recommend the users to be aware of conditions
and follow the instructions as below:
• Do not connect loads when they are dependent on a stable energy supply for a reliable opera-
tion.
• Do not connect the loads which may in total exceed the maximum back-up capacity.
• Try to avoid those loads which may create very high start-up current surges such as inverter
air-conditioner, high-power pump etc.
• Due to the condition of the battery itself, battery current might be limited by some factors
including but not limited to the temperature, weather etc.
Accepted Loads As Below:
ES series inverter is able to supply a continuous 4600VA output or maintain a 6900VA output for
less than 10 seconds on back-up side to support loads. The inverter also has self-protection
against derating at high ambient temperature.
• Inductive Load: Maximum 1.5KVA for single inductive load, maximum 2.5KVA for total inductive
load power.
• Capacitive Load: Total capacitive load (like computer, switch power etc.)power ≤3.0KVA.
(Any load with high inrush current at start-up is not accepted)
Note:
For convenient maintenance, please install a SP3T switch on back-up and on-grid side. Then it is adjustable
to support load by back-up or by grid or default settings.
1. Back-up load is supplied from back-up side.
2. Back-up load is isolated.
3. Back-up load is supplied from grid side.

Declaration For Back-Up Overload Protection
Inverter will restart itself if overload protection triggers. The preparation time for restarting will be
longer and longer (one hour at most) if overload protection repeats. Take following steps to restart
inverter immediately.
Decrease back-up load power within maximum limitation.
On PV Master App → Adcanced Setting → Click "Reset Back-Up Overload History".
