2 Overview
2.1 Product Introduction
Function
HI-3/6K-SL series, also called hybrid or bidirectional solar inverters, apply to solar system with
participation of PV, battery, loads and grid system for energy management. The energy
produced by PV system shall be used to optimize self-consumption, excess power charge
battery and the rest power could be exported to the grid. Battery shall discharge to support loads
when PV power is insufficient to meet self-consumption. If battery power is not sufficient, the
system will take power from grid to support loads.

3.3 Mounting
Installation Precaution
HI-3/6K-SL series inverter is designed for outdoor installation (IP 65).
Make sure the installation site meets the following conditions:
◆ Not in direct sunlight.
◆ Not in areas where highly flammable materials are stored.
◆ Not in potential explosive areas.
◆ Not in the cool air directly.
◆ Not in environment of precipitation or humidity (＞95%).
◆ Under good ventilation condition.
◆ The ambient temperature in the range of -20℃ to +60℃.
◆ The wall hanging the inverter should meet conditions below:
1.Solid brick/concrete, or strength equivalent mounting surface.
2.Inverter must be supported or strengthened if the wall’s strength is not enough (such as
wooden wall, the wall covered by thick layer of decoration).
Please avoid direct sunlight, rain exposure, snow laying up during.

3.5 Mounting Steps
1.Use the wall bracket as a template to mark the position of the 3 holes on the wall（unit: mm）.
2.Drill holes with driller, make sure the holes are deep enough (at least 60mm) for installation,
and then tighten the expansion tubes.
3. Install the expansion tubes in the holes and tighten them. Then install the wall bracket by
using the expansion screws. (Φ10 driller, torque: 2.5±0.2Nm)
4. Hang the inverter over the bracket, move the inverter close to it, slightly lay down the inverter,
and make sure the 2 mounting bars on the back are fixed well with the 2 grooves on the bracket.
5. After confirming the inverter is fixed reliably, fasten two M5 safety-lock sockets head cap
screws on the right or left side firmly to prevent the inverter from being lifted off the bracket
(torque: 2.0±0.2Nm).

System connection diagrams
◆ For Australian safety country, the neutral cable of Grid side and Load
side must be connected together, otherwise Load function will not work.

4.1 PV connection
◆ Conditions for DC Connection
The inverter has 2 independent inputs: PV1 & PV2 Notice that the connectors are in paired
(male and female connectors). The connectors for PV arrays and inverters are H4 connectors.

User Manual
- 13 -
◆ Connecting the PV Array
Connection Steps:
1.Choose the 12 AWG wire to connect with the cold-pressed terminal.
2.Remove 7mm of insulation from the end of wire.
3.Insert the insulation into pin contact and use crimping plier to clamp it.
4.Insert pin contact through the cable nut to assemble into back of the male or female plug.
When you feel or heard a “click” sound the pin contact assembly is seated correctly.
The solar modules connected to the inverter must conform to the
Class A requirements of the IEC 61730 standard.
If the inverter is not equipped with a DC switch but this is mandatory in
the country of installation, install an external DC switch. The following limit
values at the DC input of the inverter must not be
exceeded:
Model
Max current PV1
Max current PV2
3K-6K
15A
15A
Danger to life due to lethal voltages!
◆ PV array supplies D.C voltage to inverter when exposed to light, before
connecting the PV array, cover some light screens above PV arrays,
ensure that the DC switch and AC breaker are disconnect from the
inverter. NEVER connect or disconnect the DC connectors under load.
◆ Make sure the maximum open circuit voltage (Voc) of each PV string is
less than the maximum input voltage of the inverter.
◆ Check the design of the PV plant. The Max. open circuit voltage, which
can occur at solar panels temperature of -10℃, must not exceed the Max.
input voltage of the inverter.
◆ Improper operation during the wiring process can cause fatal injury to
operator or unrecoverable damage to the inverter. Only qualified
personnel can perform the wiring work.
◆ Please do not connect PV array positive or negative pole to the
ground, it could cause serious damages to the inverter
◆ Check the connection cables of the PV modules for correct polarity and
make sure that the maximum input voltage of the inverter is not
exceeded

5.Plug the PV connector into the corresponding PV connector on inverter.
4.2 Battery Connection
◆ Lead-Acid and other similar older-technology battery types require experienced and
precise design, installation, and maintenance to work effectively. For lead-acid battery bank,
the inconformity between battery cells might lead to battery cell over-charge or discharge, and
further might damage battery cells and shorten battery bank life.
◆ For lithium battery (pack) the capacity should be 50Ah or larger. Battery cable requirement
as below.
Table 1 Cable recommended.
◆ Please be careful against any electric shock or chemical hazard.
◆ Make sure there is an external DC switch (≥125A) connected for battery without build-in
DC switch.
Battery wiring connection steps as below:
1. Prepare battery cables and accessories and put battery power cable through battery cover.
Compress the terminal head by using a crimping pliers.
2.Connect battery terminals onto inverter.
3.Tighten screws.

4. Tighten the screw cap.
4.3 Grid & GEN & Backup Connection
An external AC switch is needed for grid connection to isolate from grid when necessary.
Connection Steps
1. Choose the appropriate wire, Wire Stripping(Cable size: refer to Table).
2.Set the parts on the cable one by one.
3.Wire crimping cord end terminal can be inserted into the housing quickly according to the
sign.
4.Insert Seal and Clamp Finger into socket, then tighten the nut.
Grid Connection:
◆ Make sure inverter is totally isolated from any DC or AC power before
connecting AC cable.

4.4 Earth Connection
Users must additionally earth the inverter to the enclosure of a second earthing or
equipotential bonding. This prevents electric shock if the original protective conductor fails.
Earth Connection Steps:
1. Strip the earthing cable insulation and insert the stripped cable into the ring terminal, then
clamp it.
2. Place the ring terminal into the earthing rod and screw the earthing screw tightly.
