CLEARANCE AND MAINTENANCE FOR ANTI-DUST KIT Overview
Every inverter is already installed with anti-dusk kit from factory. This kit keeps dusk from your inverter and increases product reliability in harsh environment.
Clearance and Maintenance
Step 1: Please remove the screws on the sides of the inverter.
Step 2: Then, dustproof case can be removed and take out air filter foam as shown in below chart.
Step 3: Clean air filter foam and dustproof case. After clearance, re-assemble the dust-kit back to the inverter. NOTICE: The anti-dust kit should be cleaned from dust every one month.
44

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. Equalization also 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 33 first. Then, you may apply this function in device by either one of following methods: 1. Setting equalization interval in program 37. 2. Active equalization immediately in program 39. 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.

terminal. The cable size used from joint to battery should be X times cable size in the tables above. “X” indicates the number of inverters connected in parallel.

Regarding AC input and output, please also follow the same principle.

CAUTION!! Please install the breaker at the battery and AC input side. This will ensure the inverter can be

51

securely disconnected during maintenance and fully protected from over current of battery or AC input. Recommended breaker specification of battery for each inverter:

Model

1 unit*

6.5KW/8KW

250A/70VDC

*If you want to use only one breaker at the battery side for the whole system, the rating of the breaker

should be X times current of 1 unit. “X” indicates the number of inverters connected in parallel.

Recommended breaker specification of AC input with single phase:

Model

2 units

6 units

6.5KW/8KW 120A/230VAC 180A/230VAC 240A/230VAC 300A/230VAC 360A/230VAC

Note 1: Also, you can use 60A breaker with only 1 unit and install one breaker at its AC input in each inverter. Note 2: Regarding three-phase system, you can use 4-pole breaker directly and the rating of the breaker should be compatible with the phase current limitation from the phase with maximum units Recommended battery capacity
