2.1 General Installation Notes

2.2 Wire Size & Breaker

•  Please read the entire installation instructions to get familiar with the installation steps before installation.
•  Be very careful when installing the batteries, especially flooded lead-acid battery. Please wear eye protection, and have
fresh water available to wash and clean if any contact with battery acid
•  Keep the battery away from any metal objects, which may cause short circuit of the battery.
•  Explosive acid battery gases may come out from the battery during charging, so make sure ventilation condition is good.
•  Ventilation is highly recommended if mounted in an enclosure. Never install the controller in a sealed enclosure with
flooded batteries! Battery fumes from vented batteries will corrode and destroy the controller circuits.
•  Lead-acid battery is only recommended, other kinds please refer to the battery manufacturer.
•  Loose connections and corroded wires may result in high heat that can melt wire insulation, burn surrounding materials,
or even cause fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in
motion.
•  Battery connection may be wired to one battery or a bank of batteries. The following instructions refer to a singular
battery, but it is implied that the battery connection can be made to either one battery or a group of batteries in a battery
bank.
•  Select the system cables according to 5A/mm2 or less current density in accordance with Article 690 of the National
Electrical Code, NFPA 70.
•  For outdoor installation, keep out of the direct sunshine and rain infiltration.
•  High voltage still exists inside the inverter/charger after switching off the power switch, do not turn on or touch the
internal units, conduct the associated operation only after discharging the electric capacity.
•  Do not place the inverter/charger in a damp, oily, inflammable and explosive or a severe environment with a large amount
of dust accumulation.
•  Prohibit reverse connection at DC input end otherwise it may damage the equipment or unpredictable danger will occur.
The utility input and AC output are of high voltage, do not touch the wire connetion.

The wiring and installation methods must follow all national and local electrical code requirements.

NOTE: When the PV modules connect in series, the open circuit voltage of the PV array must not exceed max.
PV input voltage at 250C environment temperature.

NOTE: The utility input has the circuit breaker already and there is no need to add any more.

NOTE:

Type of circuit breaker is selected based on non-independent connection of inverter at the battery end

where there is no antherinverter connected.
