Electrical Performance

Inverting

Overload Capacity

1. For 100%<Load<120%, Fault (Power off) after 10 seconds.
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.

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.

AC Charging Current:

Model	Battery Voltage	Max. AC Charging Current
4KW	48V	40A
5KW	48V	50A
6KW	48V	60A
8KW	48V	70A
10KW	48V	80A
12KW	48V	100A

MPPT Charging Current:

Model	Battery Voltage	Max. Charging Current
4-6KW	48V	80A
8-12KW	48V	120A

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.

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.

FAN Operation

For 4-6KW models, there are one DC fan and one AC fan.

For 8-12KW models, there are one DC fans and two AC fan.

The fans are designed to operate according to the following logic:

Condition	Enter Condition	Leave condition	Fan Speed
HEAT SINK TEMPERATURE	T ≤ 40°C(104°F)	T > 40°C(104°F)	OFF
	T > 40°C(104°F)	T ≤ 40°C(104°F)	ON
UTILITY CHARGER	I ≤ 20A	I>20A	OFF
CURRENT	I>20A	I ≤ 20A	ON
LOAD PERCENTAGE (INV MODE)	20% ≤ Load	Load>20%	OFF
	Load>20%	20% ≤ Load	ON

Allow at least 80CM of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit.

Output Power Derating

When DC input voltage drops to Low DC Warning Voltage OR Low DC Warning SOC, the output Voltage will be derated 10V. When transformer temperature exceed to 150°C, the output Voltage will be derated 10V.

Remote LCD Connecting (Optional)

Plug in the remote LCD panel to the RS485 port.

There's a DIP switch on the inverter communication board. Change the DIP switch setting to all "ON" as picture showed as below.

Warning:

Our cables are designed with special pinouts on the connectors, so don't use other cables, or the remote LCD panel will not be powered on.
