² wire (insulation must be rated to 300V or more). An arrow is

imprinted on the side of the CT – the arrow must point towards the load. The power supply for the

SDM120CT-MV can be taken from an existing MCB rated less or equal than 16A. If installed in the

solarZero switchboard, you may use the 16A H/W MCB or the 6A router MCB. An RS485 communication

wire must be run from the EMU in the cabinet to the SDM120Ct-MV. Cat5e or Cat6 can be used. On the

EMU an FTDI USB to RS485 adapter cable is required.

1. Generality

This document defines the technical specification for energy storage system Power pillar SG.

2. Product Model Description

3. Equipment Function

Power Pillar SG is the all-in-one energy storage system integrating PCS, battery pack and battery

management system. The battery pack is configured by a number of battery modules to store and

supply the power, which is comprehensively monitored by the BMS to protect and surveil the battery

pack. PCS has the AC-DC power converter function to store photovoltaic power or grid power into

battery and convert DC power to feedback to the grid.

4. Product Specification

4.1 BMS

High precision sampling of voltage and current

Advanced algorithm of SOC/SOH and automatic calculation on the real time of SOC/SOH

5. Storage and Maintenance

5.1. Storage

Before storing, charge the battery at least 7 hours. Store the Battery covered and upright in a cool,

dry location. Recommend long-term storage temperature is 15°C -25°C. During storage, please

recharge the battery in accordance with the following table:

Storage Temperature Recharge

Frequency

Charging Duration

-20°C - 40°C Every 3 months Do a charge and discharge cycle, the battery charge storage

5.2. Maintenance

The battery system operates with hazardous voltages. Only qualified maintenance personnel

may carry out repairs.

Even after the unit is disconnected from the mains, components inside are still connected to the

battery cells, which are potentially dangerous.

Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify

that no current is present and no hazardous voltage exists at the terminals.

Only persons who are adequately familiar with batteries and with the required precautionary

measures may replace batteries and supervise operations. Unauthorized persons must be kept well

away from the batteries.

Verify that no voltage between the battery terminals and the ground is present before

maintenance or repair. In this product, the battery circuit is not isolated from the input voltage.

Hazardous voltages may occur between the battery terminals and the ground.

Batteries may cause electric shock and have a high short-circuit current. Please remove all

wristwatches, rings and other metal personal objects before maintenance or repair, and only use tools

with insulated grips and handles for maintaining or repairing.

When replace the batteries, install the same number and same type of batteries.

When replace the parallel batteries, make sure the new battery is full charged.

Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It

may be toxic.

Please replace the fuse only with the same type and amperage in order to avoid fire hazards.

Do not disassemble the battery system.
