ATENCIÓ!!

Do not place anything between the flat part of the inverter terminal. Otherwise, overheating may occur. Do not apply anti-oxidant substance on the terminals before terminals are connected tightly. Before making the final DC connection or closing DC breaker/disconnector, be sure positive (+) must be connected to positive (+) and negative (-) must be connected to negative (-).

4.5 Connexió d'entrada/sortida de CA

ATENCIÓ!!

Before connecting to the AC input power source, install a separate AC breaker between the inverter and the AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from overcurrent of AC input. The recommended specification for the AC breaker is 63A. There are two terminal blocks with “IN” and “OUT” markings. Do not mis-connect input and output connectors.

ADVERTIMENT!

All wiring must be performed by qualified personnel. It's very important for system safety and efficient operation to use appropriate cable for AC input connection. To reduce the risk of injury, use the proper recommended cable size.

Follow these steps to implement AC input/output connection:

1. Before making AC input/output connection, be sure to open the DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. Shorten phase L and neutral conductor N by 3 mm.
3. Insert AC input wires according to the polarities indicated on the terminal block and tighten the terminal screws. Be sure to connect the PE protective conductor (yellow-green) first.
4. Then, insert AC output wires according to the polarities indicated on the terminal block and tighten the terminal screws. Be sure to connect the PE protective conductor (yellow-green) first.

Suggested Cable Requirement for AC Wires

ATENCIÓ: Important

Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility short-circuited when these inverters are worked in dual output operation. Appliances such as air conditioners require at least 2-3 minutes to restart because it's required to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check the manufacturer of the air conditioner if it's equipped with a time-delay function before installation. Otherwise, this inverter/charger will trigger an overload fault and cut off output to protect your appliance, but sometimes it still causes internal damage to the air conditioner.

6. Battery Equalization

The equalization function is added to the charge controller to reverse the buildup of negative chemical effects like stratification, where acid concentration is greater at the bottom of the battery. Equalization also helps 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 the battery periodically.

6.1 How to Apply Equalization Function

You must enable the battery equalization function in monitoring LCD setting program 17 of F2 first. Then, you can apply this function by either of the following methods:

1. Setting the equalization interval in program 21 of F2.
2. Active equalization immediately in program 22 of F2.

6.2 Quan igualar

A la carrossa stage, when the setting equalization interval (battery equalization cycle) is reached, or equalization is activated immediately, the controller will start to enter the Equalize stage.

6.3 Equalize Charging Time and Timeout

A l'Equalize stage, el controlador subministrarà energia per carregar la bateria tant com sigui possible fins que la bateria voltage puja fins al volum d'equalització de la bateriatage. Aleshores, constant-voltagS'aplica la regulació per mantenir el volum de la bateriatage a l'equalització de la bateria voltage. La bateria romandrà a l'Equalize stage until the setting battery equalized time is reached.

However, if in the Equalize stage, the battery equalized time expires and the battery voltage no puja fins al volum d'equalització de la bateriatagpunt e, el controlador de càrrega allargarà el temps d'equalització de la bateria fins que el volum de la bateriatage aconsegueix el volum d'equalització de la bateriatage. Si la bateria voltage encara és inferior al vol d'equalització de la bateriatage quan s'hagi acabat el temps d'espera d'equalització de la bateria, el controlador de càrrega aturarà l'equalització i tornarà a la posició flotant.tage.
