Safety
Danger!
Danger to life due to high voltages in the inverter!
The personnel responsible for the installation, electrical
connection, debugging, maintenance and fault handling
operation of this product need to be trained, master the correct
operation method, have the corresponding electrician
qualification and safety operation knowledge.

If the building installed with external light protection device is far
away from the inverter location, in order to protect the inverter from
electrical and mechanical damage, the inverter should also install an
external lightning protection equipment.
In order to protect DC system, two-stage surge protection equipment
is needed between DC cable of inverter and photovoltaic equipment
module.
In order to protect the AC system, the level 2 surge protection
equipment should be installed at the AC output, located between
the inverter and the grid. Installation requirements must comply with
IEC61643-21 standard.
All DC cables shall be installed in a distance as short as possible, and
the positive and negative cables of the same input need to be
bundled together to avoid causing loops in the system. Minimum
distance installation and binding requirements also apply to auxiliary
grounding and shielding grounding conductors.
07
06
Warning!
ØSurge protection devices (SPDs) for PV installation
Safety
A photovoltaic module used on the inverter must have a IEC61730A
rating, and the total open circuit voltage of the photovoltaic string /
array is lower than the maximum rated DC input voltage of the
inverter. Any damage caused by photovoltaic over voltage is not
covered by warranty.
Installation position should be away from wet environment and
corrosive substances.
After the inverter and power grid cut off the PV power supply, there
will be a certain amount of residual current in a short time, be
cautious or it may lead to serious personal injury and even high risk
of death.Use a multimeter (impedance at least 1 MΩ) to measure the
voltage between the UDC + and the UDC- to ensure that the inverter
port is discharged below the safe voltage before starting operation
(35 VDC).
Over-voltage protection with surge arresters should be
provided when the PV power system is installed.
The grid connected inverter is fitted with SPDs in both
PV input side and MAINS side.
Direct or indirect lightning strikes can cause failures. Surge is the main
cause of lightning damage to most devices. Surge voltage may occur
at photovoltaic input or AC output, especially in remote mountain
areas where long distance cable is supplied.
Please consult professionals before installing SPDs.
The external lightning protection device can reduce the inuence of
direct lightning strike, and the lightning protection device can release
surge current to the earth.

Safety
Solarever SE1-SPT Series inverter should pair with high voltage battery, for
the specic parameters such as battery type, nominal voltage and
nominal capacity etc., please refer to section 3.3.
Please refer to the matching battery specication for details.
ØBattery Safety Instructions
For United Kingdom
• The installation that connects the equipment to the supply terminals
shall comply with the requirements of BS 7671.
• Electrical installation of PV system shall comply with requirements of
BS 7671 and IEC 60364-7-712.
• All protective devices cannot be changed.
• User shall ensure that equipment is so installed, designed and
operated to maintain at all times compliance with the requirements of
ESQCR22(1)(a).
ØPE Connection and Leakage Current
• All inverter’s incorporate a certified internal Residual Current Monitoring
(RCM) in order to protect against possible electrocution and fire hazard
in case of a malfunction in the PV array, cables or inverter.
There are 2 trip thresholds for the RCM as required for certification
(IEC 62109-2:2011).
The default value for electrocution protection is 30mA, and for slow
rising current is 300mA.
The islanding effect means that when the power grid is cut off, the
grid-connected power generation system fails to detect the power
outage and still supplies power to the power grid. This is very dangerous
for the maintenance personnel and the power grid on the transmission
line.
SE1-SPT series inverters use active frequency offset method to prevent
islanding effect.
ØAnti-lslanding Effect
Warning!
High leakage Current!
Earth connection essential before connecting supply.
• A faulty ground connection can result in equipment failure, personal
and death injuries, and electromagnetic interference.
• Ensure correct according to grounding to IEC62109 and conductor
diameter according to STANDARD specification.
• Do not connect the grounding end of the equipment in series to
prevent multi-point grounding.
• Electrical appliances must be installed in accordance with the wiring
rules of each country.

IntroductionIntroduction
16 17
① Off-grid Mode
In the event of a power outage, the system will automatically switch to power
outage mode.If a specic load is overloaded, the error "independent operation
load protection" will be displayed. In this case, check whether the specic load
is within the possible range, if it is overloaded, reduce some load, and then
click the  button of "standalone load protection" displayed in the current
error in the error history to clear it and restart normally system
② Eco-friendly Mode
In the daytime, the power generated by the photovoltaic power generation
panel is supplied to the household load,
Charge the surplus in the storage battery and use it during peak hours at night
and in the morning.
It is a eco-friendly mode that emphasizes the environment. Power generation
of photovoltaic power generation panel
If there is insufficient power or there is no generated power, start with the
storage battery.
Discharge. If the storage battery is fully charged, the surplus power will be
sold.
In addition, charging from the system is performed at midnight when
electricity charges are cheap, and it is released.
Electricity is installed during the time when electricity charges are high during
the day and electricity usage is at its peak.
By setting it, you can save on electricity charges.
④Relief Mode
In the relif mode, a certain amount of remaining battery power is secured so
that you can use it with peace of mind in an emergency. The basic operation is
the same as in green mode.
⑤Manual Mode
The manual mode has three functions: forced charge, forced discharge, and
forced charge / discharge stop. Manual mode is basically available only to
maintenance personnel.
Manual charging:
This mode charges the storage battery regardless of the time of day. For
manual charging, the system charges the battery with maximum power. The
battery is charged until it is fully charged, and after the battery is fully charged,
the storage battery is in a charge / discharge stop state.
Manual discharge:
This mode discharges the storage battery to the household load regardless of
the time of day. In the case of manual discharge, the system discharges from
the battery with maximum power. After full discharge, the storage battery will
be in the charge / discharge stop state.
Charge / discharge stop:
This mode does not charge or discharge the storage battery regardless of the
time of day. Solar power is still in operation. Operate each solar power
generation other than this product.
Note: If you set the manual operation mode and there is no operation for 6
hours, it will automatically switch to the operation mode (economic mode,
safe mode, or green mode) that was used before setting the manual operation
mode.
③Economic Model
In economic model, you can save electricity bills by charging the storage battery
at night when the electricity bill is cheap and discharging it from the storage
battery during the daytime when the electricity bill is expensive. If the surplus
power of solar power generation is sold in the daytime, the storage battery will
not be discharged. The storage battery will be charged within the set time zone.
(charging time zone can be set).

Electrical Connections
Please select photovoltaic modules with good performance and
quality assurance. The open circuit voltage of the module array should
be less than the maximum PV input voltage specified by the inverter,
and the working voltage should be within the MPPT voltage range.
Table 1: Maximum input voltage limit
Warning!
The voltage of photovoltaic modules is very high, and is
dangerous voltage. When wiring, please follow the safe
electricity regulations.
Notice!
Do not ground the positive or negative pole of the
photovoltaic module!
Notice!
The following PV module requirements need to be applied to
each input range:
1. Same model
2. Same quantity
3. The same queue
4. The same angle
