Smart HF Series Single-phase PV Off-grid Inverter--Precaution
Product Introduction

Smart HF series DC/AC sine wave PV off-grid inverters are adopting a highly
effec t i ve 3 2 - b it D S P c o n t rol , a n d a hig h - fre q u e ncy t r a nsf o r m er i s o lat i o n
technology. The adjustments of output voltage and frequency, switchover of UPS
mode or PV energy saving mode can all be performed from the setting keyboard at
the front panel or from a monitoring software.
Smart HF series inverter has two applicable modes: (1) UPS mode, and (2) PV
energy saving mode. The users can adjust these modes according to demand.
When the UPS mode is selected, electricity from a local power grid flows through a
bypass circuit to all the load appliances. When the power supply of local power
grid is not stable or being shut down, the load appliances will obtain power supply
from a battery bank through the PV inverter, which is acting as a typical
uninterruptible power supply system.
If used the PV energy saving mode together with solar panels, the PV inverter
will give priority to recharge the battery bank, and supply power to all the load
appliances at the same time, thus enabling the full use of solar energy in order to
cut back the amount of electricity energy feeding by the local power grid. Only
when the battery power is lower than the battery protection shutdown point, the
power supply will be obtained from the bypass local grid or the inverter shutdown,
so as to prolong the battery life. Users can choose the correct operating mode
according to their own needs or weather conditions.
Smart HF series products can charge the battery bank through both the solar
panels and AC local grid power, and enable PV inverters to feed the AC loads while
giving a priority to use the energy from solar panels to charge the battery bank
through MPPT controllers, hence to achieve the goal of maximum energy saving.
Only use a local power grid for battery charging when the PV energy cannot
guarantee the service life of battery so as to fully ensure the battery's safety and
service life. Inside the PV inverter are an integrated solar MPPT controller and a
local grid recharger, so the users only need to connect the PV inverter with
batteries, local power grid and solar panels to set up a green energy-saving power
supply station, which can fulfill the goal of green environmental protection and
energy saving.

Do not carry out any wiring and inspection or changing components when the
power supply is applied. Hazardous voltages may still be present in the inverter
even if the external circuit breakers are all switched off. Wait at least 500 s after
switching off the inverter. This ensures that the capacitors are electrically
discharged.
Do not dispose of the product together with household waste, but only in
accordance with the locally applicable regulations for the disposal of electronic
waste.
Please read this User Manual carefully before installation.

Appliance is in compliance with CE standards.

System Operation Mode Introduction
Smart HF Series Single-phase PV Off-grid Inverter is a DC/AC pure sine wave
output inverter with digital and high efficient micro controller (CPU). The PV
inverter has both UPS mode and PV saving energy mode, which allows the user to
switch operation mode based on own needs. The PV inverter's factory default
setting is PV power saving mode, but the users can reset it to UPS mode through a
manual adjustment (Please refer to Section 3.4 for detailed operation) or
monitoring software (optional) based on the environmental and power supply
conditions.
The main difference between UPS mode and PV power saving mode is in the
proportion of energy saving. When PV inverter is set at the UPS mode and as long
the power grid can maintain a normal electricity supply, the PV inverter will switch
over to a bypass mode for supplying power to loads, and consequently the
proportion of energy saving is rather low. On the other hand, when the PV inverter
is set at the PV power saving mode, the PV inverter will take priority using the
solar power source, and consequently the proportion of energy saving is very
high. Only when the PV energy input is not available, and the battery power is
critically low will the PV inverter switch over to the power grid for a power supply. If
the power supply from a power grid is not available at this time, the system will
automatically shut down.
3.1 UPS Mode
When the PV inverter is started by a user, it will automatically use the bypass
mode to supply electricity energy directly to the loading devices. At this time,
the solar charger is charging the battery while the mains charger is shut
down. If the solar charger is not in operation, then the mains charger will
make judgment according to the battery voltage sampling value for whether
or not to charge the battery. If the battery voltage falls below the start
threshold voltage of the mains charger at 50V, the mains charger will charge
the battery all the time. If the battery voltage is higher than the start threshold
voltage of the mains charger, then the mains charger will not work.

When the battery capacity is fully charged to 55V, the solar charger will enter
the floating charge state to charge the battery. At this point, it is still the
bypass mode to supply power to the loads.
If the mains power outage happened instantaneously or the mains power has
exceeded the constant voltage input range, the PV inverter will automatically
and immediately switch over to the inverter output power so as to replicate the
power supply of loading devices, and guarantee that there is no interruption
or damage to the devices caused by an unstable mains power or power
outage, and hence subsequently causing unnecessary economic losses to
the users.
If the mains power is restored to a normal condition, the PV inverter will
automatically switches to the bypass mode and resume mains power to the
loads.
If the mains power remains cutoff and in the case of the PV charging energy is
less than the energy required by loads, the voltage of battery will gradually
decrease. When the battery voltage is below 45Vthe PV inverter will rapidly
start beeping an alarm at a frequency of about 1 second at a time. When the
battery is almost drained completely, the PV inverter is about to shut down.
When battery voltage falls to 43V, the battery power is almost completely
drained. If the mains power is still not available at this time, the PV inverter
will automatically shut down its output. At this stage, the PV inverter remains
in a standby mode and waiting for the mains power to restore and the input of
PV energy.
If the user turns the PV inverter's power switch to the OFF position at this
moment, the inverter is shut down completely. The user needs to manually
turn the power switch of PV inverter to the ONposition in order to restart the
inverter. If the PV inverter stays in a standby mode and when the mains power
is restored, the inverter will automatically switch to the bypass mode to
supply power for the loads. The PV inverter will also start to use the mains
power charger to charge the battery so as to prolong the service life of battery.
If the mains power supply remains cutoff but PV energy input is available, the
PV inverter will automatically turn on the solar charger to recharge the
battery, and at this stage the PV inverter has no output. When the solar
charg er has c harged t he batte ry vo ltage to 52 V, the P V i nv erter wi ll
automatically initiate the inverter output power for supplying power to the
loads.
Smart HF Series Single-phase PV Off-grid Inverter--System Operation Mode Introduction
UPS mode is not available for HFP series products.
When the mains power supply is cut off, the PV inverter's output power
supplying time is depended on the battery capacity and the amount of loads
being used.
The advantage of UPS mode is that the battery capacity will generally be
maintained at a level higher than 90% in order to ensure an adequate power
supply to the loading devices in the event of a short period utility power
outage. As the number of deep discharge of the battery is reduced, and the
battery service life is closely related to the numbers of deep discharge, hence
the UPS mode can significantly extend the service life of battery. Since UPS
mode is of low energy saving efficiency, it is suitable to use in places like the
commercial offices and residential areas where the mains power supply is
available and relatively stable.
Remarks:

3.2 PV Energy Saving Mode
After the user starts up the PV inverter, it will automatically switch to the
inverter output to supply power to the loading devices, and start the solar
charger to charge the battery.
When the PV charging energy is lower than the energy required by the loads,
the battery voltage will gradually decrease. When the battery voltage is below
45V, the PV inverter will start rapid beeping alarm at a frequency of about 1
beep per second to alert the users that the battery power is about to run out. If
the mains power input is normal, then the PV inverter will start off the mains
power charger to charge the battery.
When the battery voltage falls to 43V, the battery power is almost exhausted.
If the input of mains power is normal at this time, the PV inverter will
automatically switch to the bypass mode so as to allow the mains power to
supply the loading devices. The PV inverter at the same time will start the
mains power charger for charging the battery. If solar charger has charged the
battery, then shut down the mains charger as the purpose of energy saving is
achieved. If the mains power input is not available at this stage, the PV
