Introduction

HiEnergy Series is a high-quality system which can convert solar energy to AC energy

equipped with storage battery. It's an all-in-one system. HiEnergy inverter is only

compatible with HiEnergy batteries (HEC2-BHP) and currently is not compatible with

other batteries (include other LFP battery and Lead acid battery)

The HiEnergy Series system can be used to optimize self-consumption, store electricity

in the battery for future use or feed electricity into public grid. Work mode depends on PV

energy and user’s preference. It can provide electricity for emergency use during the grid

lost by using the energy from battery and inverter generated from PV.

3.1 Basic Features

3 Introduction

User Manual

System Diagram

Figure1 DC-coupled Storage System – Scheme

Figure 2 AC-coupled Storage System – Scheme

13 Introduction

There are three basic work modes that end users can choose via inverter APP.

• Self Use:

The energy generated by the solar panels will

be used in the following order: supply to the

home loads; charge the battery and then, feed

into the grid. When the PV power is not

available, the load will be supported by battery

to enhance self-consumption. If the power

supply from the batteries is not sufﬁcient, the

grid will support the load demand.

• Back up:

Under this mode, the battery is only used as a

backup power supply when the grid fails, as

long as the grid works, the batteries won’t be

used to power the loads. The battery will get

charged with the power generated by the PV

system or from the grid.

• Peak Saving:

This mode is designed for time-use mode

customer. The customer is able to set up the

charging/discharging time & power via APP.

5.4 Communication Interface Connection

This interface is connection to electricity meter or CT. The electricity meter should be

mounted and connected at the grid transition point (feed-in point) so that it can measure

the grid reference and feed-in power. The communication about PCS and meter/CT is

RS485.This port is used for 485 communication between 2 external CT channels and an

electric meter. Currently CT1 is enabled and CT2 is reserved. The meter communication

uses RS485 interface to read the voltage, current, active power, reactive power, apparent

power and other information collected by the meter. Before communicating with the

meter, the baud rate and address information of the meter need to be set through the

“Solarman Business APP”.

For Australia, New Zealand. The neutral points on the GRID side and the LOAD side must

be connected together, otherwise the LOAD function does not work.

PE grounding:

1. The PE terminal of LOAD is vacant and cannot be connected to the grid system of

Australia, New Zealand and South Africa.

2. There are two PE earthing posts on the PCS shell, one is connected to the shell earth-

ing post of the BMS control box to maintain earthing continuity between different struc-

tural parts, and the other PE earthing post needs to be reliably connected to the building

earthing ring network nearby.

HEC Hybrid Series is designed with two EPS versions for customer to choose based on

the local rules.

E Version applies to the wiring rules that requires the Live line and N (Neutral) line of

EPS must be disconnected with the Live line and N (Neutral) line of grid (applies tomost

countries).

User Manual

8.2 Maintenance During Operation

1. In the process of inverter commissioning, regularly check whether the inverter wirings

are ﬁrm, and check whether the dust net, fan, power module, terminals and other parts are

working normally.

2. The inverter cabinet has high pressure, usually should pay attention to check whether

the cabinet door is locked or not.

3. When the room temperature exceeds 30℃, effective cooling measures should be taken

to prevent the inverter from overheating and burning.

4. The structure and electrical connection of the inverter should be kept intact, and there

should be no corrosion, accumulation of dust, etc. The inverter should not have large

vibration and abnormal noise during operation.

5. Regularly disconnect the circuit breaker of AC output side of the inverter once.

6. When the DC bus capacitor temperature in the inverter is too high or exceeds the

service life, it should be found and replaced in time.

7. the inverter belongs to high reliable operation equipment, can achieve long-term

trouble-free operation, weekdays should carry out inspections, listen to the inverter sound

is normal, the external debris, whether the vent is dusty, the panel display is normal, found

that the problem is dealt with in a timely manner, report.

Note: Non-professionals should not disassemble and overhaul the inverter without

permission. Inverter generally have short circuit, over current, over voltage, overheating

and other items of automatic protection, when the problem occurs, do not need to manu-

ally shut down.
