3. Introduction
3.1 Basic features
Hybrid Series is a high-quality inverter which can convert solar energy to AC energy
and store energy into battery.
The inverter can be used to optimize self-consumption, store in the battery for
future use or feed in to public grid. Work mode depends on PV energy and user’s
preference. It can provide power for emergency use during the grid lost by using
the energy from battery and inverter (generated from PV).
3.2 System Diagram
Hybrid Series is designed with two BACK-UP versions for customer to choose based
on the local rules. The applies to the wiring rules that requires Neutral line of
alternative supply must NOT be isolated or switched.

2.2 Explanation of Symbol
This section gives an explanation of all the symbols shown on the inverter and on
the type label.
Symbols on the Type Label
UL certified
This symbol indicates that you should wait at least 5mins after disconnecting the
inverter from the utility grid and from the PV panel before touching any inner live
parts.
eep dry! The package/product must be protected from excessive humidity
and must be stored under cover
.
Refer to the operating instructions.
ragile - The package/product should be handled carefully and never
be tipped over or slung.

No more than six(6) identical packages being stacked on each other
Components of the product can be recycled.
Danger of hot surface!
Danger of high voltage and electric shock!
Caution! Failure to observe a warning indicated in this manual may result in injury

10
All switches and RCD devices in the figure are for reference only, and the specific
installation shall be subject to local regulations.
Note!
Please control the home loads, and make sure it’s within
the “BACK-UP output rating” under BACK-UP mode,
otherwise the inverter will shut down with an “overload fault”
warning.
Please confirm with the mains grid operator whether there
is any special regulations for grid connection.
11
Note!

voltage of module arrays connected in series should be less than Max. DC input
voltage; operating voltage should be conformed to MPPT voltage range.
Warning!
PV module voltage is very high, which already achieve dangerous voltage
range, please comply with electric safety rules when connecting.
Please do not make PV positive or negative ground !
Note !
The following requirements of PV modules need to be applied for each
input area;
Please do not make PV positive or negative ground!
In order to save cable and reduce the DC loss, we suggest to install the
inverter near PV modules.

6.3 Back-up:Load1 and Load2 Connection
Inverter has On and Offgrid function, the inverter will deliver output power through
AC port when the grid is on, and it will deliver output power through back-up port
when the the grid is off.
Auto & Manual
BACK-UP function can be achieved automatically or manually according to
user’s wishes. BACK-UP function can only be triggered automatically.
Load1 port: important load.
Load2 port: When the battery is not sufficient, the load on this interface will
power down
1). For inverter, 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. It shall not
cover the standard warranty and be liable for any consequences arising from
users not following this instruction.
2). Hybrid inverters are able to supply over load output at its “Back-Up”. For
details, please refer to the technical parameters of inverter. And the inverter has
self-protection dreading at high ambient temperature.
3). For complicated application, or Special load ，please contact after-sales.

Back-Up: Load1 and Load2 Connection:
When using the off-grid function, please add off grid AC breaker in off grid
output cable to ensure safety.
Note: The absence of AC breaker on back-up side will lead to inverter damage
if an electrical short circuit happens on back-up side.
Step1.Make BACK-UP wires.

Step2. Connect the cables to the BACK-UP: Load1 and Load2 port of the
inverter.
Inside the inverter, load2 is connected to load1 through a relay, and the relay
disconnect when the SOC of battery is lower than set value. At this time,the load2
is powered off and load1 is still powered on.(The total power of Load1 plus Load2
should not more than the rated BACK-UP power when GRID is off)

Requirements for BACK-UP load
Waring!
Make sure the BACK-UP load power rating is within BACK-UP output
rating, otherwise the inverter will shut down with an “over load”
warning.
When an “over load” is appeared, adjust the load power to make sure it
is within the BACK-UP output power range, then turn the inverter back on.
For the nonlinear load, please make sure the inrush power should be
within the BACK- UP output power range.
6.4 Battery Connection
Charging & discharging system of Hybrid series inverter is designed for 48V lithium
battery.
Before choosing battery, please note the maximum voltage of battery cannot
exceed 60V and the battery communication should be compatible with Hybrid
inverter.
Battery breaker
Before connecting to battery, please install a no-polarized DC breaker to make sure
inverter can be securely disconnected during maintenance.

BMS PIN Definition
Communication interface between inverter and battery is RS485 or CAN with
a RJ45 connector.
When using RS485 protocol, please note that PIN2 must be disconnected！
Note！
The battery communication can only work when the battery BMS is
compatible with the inverter.
Power Connection Battery:
Step1
Choose the 1 AWG wire and strip the cable to 15mm. Select two O-terminals
with an aperture of M10. Insert the stripping line into the O-terminal and
clamp it with a crimping clamp.
Step2. Cross the battery cable although the battery port. Connect battery
cable to battery terminal

6.8 E-Stop Installation
The emergency stop (E-stop) button (D) included with this inverter is used to stop
the PV modules from passing voltage on the string conductors, leaving them at a
safe voltage for first responders to perform work in or on the building.
The e-stop button is a normally closed (NC) contact. When the button is pushed,
the state of the e-stop is open.
Two 18-22AWG wires are used for connection between e-stop and inverter. At the
inverter, these conductors are terminated at the 10 pin connector in the middle of
the communication board, and the two conductors are respectively connected to
DRY1_ 1B and DRY1_ 1。At e-stop, the conductor is connected to the back of the
contactor.
