shortage occurs and recovers in a short time, it will cause damage to your connected appliances.
To prevent this kind of damage, please check with manufacturer of air conditioner that if it‟s
equipped with time-delay function before installation. Otherwise, this off grid solar inverter will
trigger overload fault and cut off output to protect your appliance, but sometimes it still causes
internal damage to the air conditioner.

2. For 120%<Load≤300%, Fault (Power off) after the 5 seconds.
Soft Start in Inverter Mode
When the inverter is turned on, the output voltage gradually ramps up from 0VAC to rated voltage in about 1.2 sec.
This effectively reduces otherwise very high starting inrush current drawn by AC loads such as Switched Mode Power
Supplies and inductive loads. This will result in lower motor inrush current, which means less impact on the loads and
inverter.
Caution:
After the inverter is switched on, it takes a finite amount of time to self-diagnose and get ready to deliver full power.
Always switch on the load(s) after a few seconds of switching on the inverter. Avoid switching on the inverter with
the load already switched on. This may prematurely trigger the overload protection. When a load is switched on, it
may require an initial higher power surge to start. If multiple loads are being powered, they should be switched on
individually so that the inverter is not overloaded by the higher starting surge.

12
AC Charger
The inverter is equipped with an active PFC (power factor correction) multistage battery charger. The PFC feature is
used to control the amount of power used to charge the batteries in order to obtain a power factor as close as
possible to 1.
When AC voltage is in the range of 154~260VAC, the charging current is 100%. Once it exceeds 260VAC, it must be
restored to 250VAC before it can be charged.
The inverter/charger has a very rapid charge current available, and the max charge current can be adjusted from 10A
to 100A in small increments on the inverter‟s LCD. This is helpful if this powerful charger applies charging to a small
capacity battery bank.
There are mainly 3 stages:
Bulk Charging: This is the initial stage of charging. While Bulk Charging, the charger supplies the battery with
controlled constant current. The charger will remain in Bulk charge until the absorption charge voltage is achieved.
Absorb Charging: This is the second charging stage and begins after the absorb voltage has been reached. Absorb
charging provides the batteries with a constant voltage and reduces the DC charging current in order to maintain the
absorb voltage setting.
In this period，the inverter will start a T1 time; the charger will keep the boost voltage in Boost CV mode until the T1
time has run out. When charging current is <0.01C or the time is over 12 hours, then drop the voltage
Down to the float voltage.
Float Charging: The third charging stage occurs at the end of the absorb charging time. During float charging, the
charge voltage is reduced to the float charge voltage. In this stage, the battery are kept fully charged and ready if
needed by the inverter.

Battery Equalization
Equalization function is added into charge controller. It reverses the buildup of negative chemical effects like
stratification, a condition where acid concentration is greater at the bottom of the battery than at the top.
Equalizationalso helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this
condition, called sulfation, will reduce the overall capacity of the battery. Therefore, it‟s recommended to equalize
battery periodically.
How to Apply Equalization Function
You must enable battery equalization function in monitoring LCD setting program 23 first. Then, you may apply this
function in device by either one of following methods:
1. Setting equalization interval in program 27.
2. Active equalization immediately in program 28.
When to Equalize
In float stage, when the setting equalization interval (battery equalization cycle) is arrived, or equalization is active
immediately, the controller will start to enter Equalize stage.
Equalize charging time and timeout
In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage raises
to battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage at the
battery equalization voltage. The battery will remain in the Equalize stage until setting battery equalized time is
arrived.
However, in Equalize stage, when battery equalized time is expired and battery voltage doesn‟t rise to battery
equalization voltage point, the charge controller will extend the battery equalized time until battery voltage achieves
battery equalization voltage. If battery voltage is still lower than battery equalization voltage when battery
equalized timeout setting is over, the charge controller will stop equalization and return to float stage.

14
Power Saver
The “Power Saver” function is dedicated to conserve battery power when AC power demand is either minimal or not
required at all by the loads.
In this mode, the inverter pulses the AC output looking for an AC load (i.e., electrical appliance). Whenever an AC
load (greater than 500 watts at 120Vac) is turned on, the inverter recognizes the need for power and automatically
starts inverting and output goes to full voltage. When there is no load (or less than 500 watts) detected, the inverter
automatically goes back into search mode to minimize energy consumption from the battery bank.
In “Power saver on” mode, the inverter will draw power mainly in sensing moments, thus the idle consumption is
significantly reduced.
