INSTALLATION Unpacking and Inspection Before Installation, please Inspect the unit. Be sure that nothing Inside the package is damaged. You should have received the following items inside of package: * The unit 1 * User manual x 1 + Communication cable x 1 Preparation Before connecting all wiring, please take off bottom cover by removing two screws as shown below. Mounting the Unit Consider the following points before selecting where to Install: Da not mount the Inverter on flammable construction materials.
Install the ult by screwing three screws. 1-3KVA 24V 2-3KVA 24V Plus, 4-5KVA 48V modal Battery Connection CAUTION: For safety operation and regulation compliance, Its requested to Install a separate DC over-current protector or disconnect device between battery and inverter. It may not be requested to have a disconnect device In some applications, however, It's still requested to have over current protection Installed. Please refer to typical amperage in below table as required fuse or breaker size.
Please follow below steps to Implement battery connection: 1. Assemble battery ring terminal based on recommended battery cable and terminal size. 2. Connect all battery packs as units requires. IV's suggested to connect at least 100th capacity battery for 1-3KVA model and at least 200th capacity battery for 4KVA/SKVA model. NOTE: Please only use sealed lead acid battery or sealed MAGELLAN lead-acid battery. 3.
AC Input/Output Connection CAUTION II Before connecting to AC Input power source, please Install a separate AC breaker between inverter and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC Input. The recommended spec of AC breaker Is 104 for AKIVA, 20A for AKIVA, 32A for AKIVA, 404 for AKIVA and 50A for SKA. CAUTION There are two terminal blocks with “IN” and “OUT” markings.
5. Make sure the wires are securely connected. CAUTION: 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 word in parallel operation. CAUTION: Appliances such as air conditioner are required at least 23 minutes to restart because Its required to have enough time to balance refrigerant gas Insole of cults.
PV Module Selection: When selecting proper PY modules, please be sure to consider below parameters: 1. Open circuit Voltage (Voc) of PV modules not exceeds max. PY array open circuit voltage of inverter. ultra Voltage (Voc) of PY modules should be higher than min. battery voltage. Solar Charging Mods. AKIVA 24V AKIVA 24V INVERTER MODEL AKIVA 24V Plus/ AKIVA AKVA/SKVA AKIVA 24V 24V Plus Max. PY Array Open Circuit Voltage 75vdc max 145vdc PV Array MP FT Voltage Range 30~66Vdc 30~115Vdc 60~115Vdc Min.
Communication Connection Please use supplied communication cable to connect to Inverter and PC. Insert bundled CD Into a computer and follow on-screen Instruction to Install the monitoring software. For the detailed software operation, please check user manual of software Inside of CD. Dry Contact Signal There is one dry contact (3A/250VAC) available on the rear panel. It could be used to deliver signal to external device when battery voltage reaches warning level. Unit Status.
