01 INTRODUCTION
GoodWe BH series bidirectional inverter is designed for both indoor and
outdoor use, which could be used with or without existing grid-tied inverter
systems to store energy using batteries. Energy produced from the grid-tied
inverters will be used to optimize self-consumption, excess will be used to
charge the battery, anymore could be exported to the grid. Loads will be
supported in priority by grid-tied system, then battery power, if more power
is needed, energy will be imported from the grid.
Note:
The introduction describes a general behavior of BH system.
The operation mode can be adjusted on PV Master App
depending on the system layout. Below are the general
01
operation modes for BH system:

Please contact GoodWe after sales for the special firmware and adjust methods.
Declaration For Back-Up Function
The back-up output of BH hybrid inverters have over load ability.
For details please refer to the technical parameters of BH series inverter
section (Page **).
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 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: · Do not connect loads if they are dependent on a stable energy supply
for a reliable operation
· 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 battery
itself, battery current might be limited by some factors includ-
ing but not limited to the temperature, weather etc.
Accepted Loads As Below:
BH series hybrid inverters are able to supply over load output at it’s Back-
Up. For details please refer to the technical parameters of BH series inverter
(4.3 section). And the inverter has self-protection derating at high ambient
temperature.
· Inductive Load: 1.5P non-frequency conversion air-conditioner can be connect
to back-up side. Two or more non-frequency conversion air-conditioner connect
to Back-Up side may cause UPS mode unstable.
· Capacitive Load: Total power <= 0.6 x nominal power of model. (Any load with
high inrush current at start-up is not accepted.)
· For complicated application, please contact after-sales.
Note:
For a convenient maintenance, an DP3T support could be installed on Back-Up
and On-Grid
13 side. Then it is adjustable to support load by Back-Up or by grid or just
leave it there.

Questions & Answer (Q&A)
About Wi-Fi Configuration
Q: Why can’t I find the Solar-WiFi signal on mobile devices?
A: Normally Solar-WiFi signal could be searched right after inverter has
powered up. But Solar-WiFi signal will disappear when EM connects to internet.
If changes to the setting are required, connect to the router for change. If
you can’t find the WiFi signal or connect to the router, then please try to
reload Wi-Fi (please refer to “3.1 Wi-Fi Configuration”).
Q: Why can’t I connect Solar-WiFi* signal on my phone?
A: The Wifi module can only connect to one device at a time. If the signal is
already connected to another device at the time for some reason, you cannot
connect to the signal.
Q: Why does the Wi-Fi module fail to connect to network after I choose the right router hotspot and enter the right passwords?
A: It’s possible that there are special characters not supported by module in the hotspot
23
passwords. Please modify the password to consist of only Arabic numerals or uppercase
/lowercase letters.
About Battery Operation Q: Why does the battery not discharge when grid is not
available, while it discharges
normally when grid is available? A: On the App, off-grid output and back-up
function should be turned on to make battery
discharge under off-grid mode.
Q: Why is there no output on back-up side? A: For back-up supply, the “Back-Up
Supply” on PV Master App must be turned on. Under off-grid
mode or when grid power is disconnected, “Off-Grid Output Switch” function
must be turned on as well.
Note: When turning “Off-Grid Output Switch” on, don’t restart inverter or
battery, otherwise the function will be switched off automatically.
Q: On Portal, why battery SOC has a sudden jump up to 95%? A: This normally
happens on when BMS communication fail on lithium. If battery enter float
charge, SOC will be reset to 95% compulsively.
Q: Why battery cannot be fully charged to 100%? A: Battery will stop charge
when battery voltage reaches charge voltage set on PV Master APP.
Q: Why battery breaker always trip when starts it up (Lithium battery)? A: The
breaker of lithium battery normally trips for following reasons:
1. BMS communication fails. 2. Battery SOC is too low, battery trips to
protect itself. 3. An electrical short-cut happened on battery connection
side. Or other reasons please con-
tact After-sales for details.
Q: Which battery should I use for BH? A: For BH series inverter, it could
connect lithium batteries which have compatibility with BH series inverter
with nominal voltage from 85V to 450V. Compatible lithium batteries can see on
battery list in PV Master APP.
About PV Master Operation and Monitoring Q: Why can’t I save settings on PV
Master App? A: It could be caused by losing connection to Solar-WiFi .
1. Make sure you have already connected Solar-WiFi (make sure no other
devices connected) or router (if connected Solar-WiFi* to router). APP’s
homepage shows connection well.
24
2. Make sure you restart inverter 10mins after you change some settings
because inverter will save settings every 10 mins under normal mode. We
recommend to change setting parameters when inverter is in wait mode.
Q: Why are the data displayed on the homepage different from the param page,
like charge/discharge, PV value, load value or grid value?
A: The data refresh frequency is different, so there will be a data
inconformity between different pages on the App as well as between these on
portal and App.
Q: Some columns show NA, like battery SOH, etc. Why does that happen? A: NA
means App does not receive data from inverter or server because of
communication
problem, such as battery communication, and communication between inverter and
the App.
About Smart Meter And Power Limit Function Q: How to activate output power
limit function? A: For BH system, the function could be realized by:
1. Make sure Smart Meter connection and communication well. 2. Turn on export
power limit function and set the max output power to grid on App. Note: Even
if output power limit is set to 0W, there might still be a deviation of a max
of 100W
exporting to grid.
Q: Why is there still power exporting to grid after I set power limit as 0W?
A: Export limit could be 0W theoretically, but there will be a deviation of
around 50-100W for BH
system.
Q: Can I use other brand Meter to take over Smart Meter in BH system or change
some settings on Smart Meter?
A: No, because the communication protocol is integrated into inverter and
Smart Meter, other brand meters cannot communicate. Also any manual setting
change could cause Meter communication failure.
Q: What is the maximum current allowed to go through CT on Smart Meter? A: The
max current for CT is 120A.
Other Questions
Q: Is there a quick way to make the system work?
A: For the shortest way, please refer to “BH Quick Installation Instructions” and “PV Master App
25
Instruction”.
Q: What kind of load can I use to connect on Back-Up side?
A: Please refer to “2.4.2 On-Grid & Back-Up Connection: Declaration For Back-
Up Overload Protection”.
Q: Will the warranty of the inverter still be valid if for some special
conditions we cannot 100% follow the user manual instructions on the
installation or operation?
A: Normally we still provide technical support to problems caused from
disobeying the instructions on the user manual, however we cannot guarantee
any replacements or returns. So if there is any special conditions where you
cannot 100% follow the instructions, please contact after-sales for
suggestions.

SOLUTIONS
1. Check (use multi-meter) if AC side has voltage . Make sure grid power is
available. 2. Make sure AC cables are connected tightly and right well. 3. If
all is well, please try to turn off AC breaker and turn on again after 5 mins.
1. Make sure safety country of the inverter is set right. 2. Check (use
multi-meter) if AC voltage (Between L & N) is within a normal range (Also on
AC breaker side)
a. if AC voltage is high, then make sure AC cable complies with that required
on user manual and AC cable is not too long.
b. if voltage is low, make sure AC cable is connected well and the jacket of
AC cable is not compressed into AC terminal. 3. Make sure the grid voltage of
your area is stable and within normal range.
1. Make sure safety country of the inverter is set right. 2. If safety
country is right, then please check on inverter display if AC frequency (Fac)
is within a normal range. 3. If FAC failure only appear a few times and
resolved soon, it should be caused by occasional grid frequency unstability.
Check use multi-meter if there if there is high voltage (normally should be
lower than 10V) between N&PE cable on AC side. If the voltage higher than 10V,
it means the Netural & ground cable are not connected well on AC side or
restart inverter.
1. Try to decrease surrounding temperature. 2. Make sure the installation
complies with the instruction on inverter user manual. 3. Try to close
inverter for 15 mins, then start up again.
