(3) Press the “ON” button, observe the instructions shown on the display, and make sure the device starts running. (4) Connect the rated loads to AC output sockets, observe the display and check whether the device is working properly. (5) DIP switches

- ! -14

User Manual On the front panel of inverter, there are 5 DIP switches which enable users to customize the performance of the generator.

SW1: Low Battery Trip Volt:

SW1 for sealed car battery, this is to prevent batteries from over-discharging while there is only a small load applied on the inverter.

SW2: AC Input Range:

There are different acceptable AC input ranges for different kinds of loads. For some relatively sensitive electronic devices, a narrow input range(SW2=0) is required to protect them. While for some restive loads which work in a wide voltage range, the input AC range can be customized to a wide input range(SW2=1), this helps to power loads without frequent switches to the battery bank. In order to make the inverter accept dirty power from a FUEL POWERED generator, when the SW2 is switched to position“1” , the inverter will bypass an AC input with a wide voltage and frequency(40Hz-70Hz for 50Hz/60Hz). Accordingly, the AC charger will also work in a wide voltage and frequency range generator. But some sensitive loads will suffer from the low quality power. The pros and cons should be clearly realized.

SW3: Power Saver Auto Setting :

In Power Saver Mode, when the SW3 is switched to position“0”, inverter will work in Unit Off Charging mode, it will stay in standby mode without sensing loads. It won’t output any power even if a load is turned on. The inverter will not perform any function and only stay idle in this mode. When a qualified AC input present, it will switch to AC input power to charge the battery and supply the load at the same time. When the SW3 is switched to position“1”, the inverter is initially in standby mode and sends a pulse to detect the presence of a load every 3 seconds. Each pulse lasts for 1s. The inverter will remain in standby

User Manual mode until a load has been detected, then it will wake up from standby mode and start to inverter electricity from the battery bank to supply the load.

SW4: Frequency Switch:

The output frequency of the inverter can be set at either 50Hz(SW4=0) or 60Hz(SW4=1).

SW5: Solar Mode/AC Mode Priority:

When the SW5 is switched to position“0”, the inverter is in Utility Priority. This means, utility will power the load and the battery will also be charged by utility. Only when the AC power is unavailable, the inverter will transfer the DC power output from battery to power the load. And when the SW5 is switched to position“1”, the inverter will transfer power from battery despite the AC input. Only when the battery voltage reaches low voltage alarm point(11.5V for 12V), the inverter will transfer to AC Input, charge battery, and switch back to battery when battery is almost charged full(13.5V for 12V). This function is mainly for wind/solar systems taking utility power as back up.

3.3.3 Other features Auto Generator Start (AGS) The inverter can be customized to start up a generator when battery voltage goes low. When the inverter goes to low battery alarm(11.5V for 12V), it can send a signal to start a generator, and turn the generator off after battery charging is finished.

The auto generator start feature will only work with generators designed to work with this feature. There is an open/closed relay that will short circuit the positive and negative cable from a generator. The input DC voltage can vary, but the Max current the relay can carry is 16Amp.

Battery temperature sensor (BTS) A battery temperature sensor (BTS) option can easily be installed in the system to ensure proper charging of the batteries based on temperature. Installing a BTS extends battery life by preventing overcharging in warm temperatures and undercharging in cold temperatures.

4 WARNING

Never leave the loads unattended, some loads (like a Heater) may cause an accident in such cases. It is better to shut everything down after low voltage trip than to leave your load on, due to the risk of fire.
