1. Equipment Introduction
ME-3000SP is mainly applied and developed for the renewable energy generation system compatible with lead-
acid batteries and lithium batteries. It can help to achieve the optimal of battery power automatically. ME 3000SP
can control the off-grid, on-grid and the bi-directional flow of electric power, work under the auto / manual mode
and time-of-use (TOU) price mode, automatically switch to the off-grid and on-grid work mode and manage the
battery charge / discharge, etc. Also, the inverter has the intelligent on-grid discharge function by setting and can
adjust its discharge power according to the change of the load power, avoid the feed of redundant power into the
power grid and help the user to make the maximum benefit. This storage inverter can choose DC bus occasion in
connection with the PV system and also be used as a pure off-grid inverter if there is no PV system. The equipment
is equipped with an LCD display panel and keyboard, high-quality Human Machine Interface and is stable, safe and
reliable. The monitoring software has the fault history recording function for later-stage maintenance.

Otherwise, the battery might leak and fire or crack.
The connection cable shall not be extended from the provided cables to avoid too much voltage drop.
Before switching on the batteries, check the connection are correct according to the manual, check the total
voltage and anode and cathode of the battery system to ensure the correct installation.
If you want to store the batteries without using them, they should be disconnected from the Charger, and kept
in a cool, dry and ventilated environment.
Please be noted that it is not necessary to provide the reservation information with the following exact measures:
Battery maintenance operators shall have the know-how and technical skill for the maintenance of the battery;
When the battery is changed, the battery bank of the same model, firmware and quantity shall be changed;
Warning: Do not dispose of scrap batteries with fire. Otherwise, the batteries might explore.
Warning: Do not dismantle or damage the battery. Its electrolyte might be toxic and damage your skin and
eyes.
Warning: The battery may cause an electric shock or short circuit. Please take the following measures for the
battery work:
a) Take off your watch, ring or other metal objects.
b) Only use tools with insulated handles.
c) Wear rubber gloves and shoes.
d) Do not put tools and metals above the battery.
e) Switch off the charge power supply before the battery terminal is disconnected.
f) Check if the battery is connected to the ground. If so unconsciously, disconnect the battery from the ground.
Any part that touches the ground battery may suffer an electric shock. Disconnect the battery from the ground
during installation and maintenance, so as to reduce the possibility of such a shock (applicable to the
equipment and remote power supply without power circuits connected to the ground).

4. Electrical Connection
Be aware of electric shock and chemical hazards!
Before connecting the battery, ensure the cable connectors have the correct polarity. Reversed polarity will
damage the inverter!
Before connecting to battery, please install a separate DC breaker (100A) between inverter and battery. This will
ensure the inverter can be securely disconnected during maintenance.
Before connecting to Grid, please install a separate AC breaker (25A) between inverter and grid.
It is very important for system safety and efficient operation to use appropriate cable for electrical connection.
Battery connection: cable of AWG8 or AWG6.
Grid & Load connection: cable of AWG12.
Make sure N wire is connected to PE wire when ME3000SP is working in EPS (Emergency Power Supply) mode.

Long Power Cable connection
If you have a single or multiple batteries, once connected your bank of battery power needs to be
connected to the SoFar Me3000SP unit. This cable is 2m long – which is the maximum distance possible
between the battery bank and the SoFar Me3000SP unit. Connect the long power leads to the GRID
positive and negative on the SoFar Me3000SP unit, and to the relevant positive and negative connections
On the battery as shown in figure 8.

CT Connections
There are 2 CT clamps which need to be connected. One is around the AC supply coming into the property, and the
other is around the AC feed from your renewable source to the fuse-board.
If you are installing close to the fuse-board then you may only need a short extension. If you need a longer run, as
you are locating the unit further away, you will need a longer extension.
Use Data cable to make this extension as this will ensure no interference from other devices when running longer
distances. Follow the chart below to see how to group the cables, and the image in figure 8 in order to make the
extension and to fit the sensor on the cable facing the correct direction.
