KEY POINTS SUMMARY:
1.
Each Lithium Battery contains circuitry that protects the Lithium Ferro Phosphate cells from overcharging,
over-discharging, and excessive load amperage. If the values specified are exceeded, the battery will enter a
protective shut down state. In some cases, this may result in the need to re- initialize an inverter charger or
other equipment in the installation. In other cases, the inverter’s systemsettings may be saved within the
inverter memory storage and will not need to be reset. This is not an
absolute standard but is common among most inverter chargers. Check your inverter manufacturer
specifications.
2.
If the battery enters a self-protective mode, negligible voltage readings will be present until the unit is reset.
In some instances, after unused for long time, a charge might need to be manually applied to the energy storage
bank. Should this occur, please contact ENSMART for technical support. Lithium Batteries are designed to remain
robust and safe under most circumstances.
3.
Although each Lithium Battery contains circuitry that protects the Lithium Ferro Phosphate cellsfrom
overcharging, over-discharging and excessive load amperage, Lithium Batteries must alwaysbe installed with
a charge controller and the appropriate settings to protect the batteries from openPV and other high voltage
sources. Lithium Batteries alone will not protect from extreme electrical phenomena.
4.
GRID TIED SYSTEMS: Once the Lithium Battery has been installed, turn on the entire systemto test. Once
testing has been completed, please disconnect the batteries from the load center until your local Utility
Inspector is ready to turn on the entire system. The charge controllers and inverter monitoring systems can
drain the Lithium Batteries over an extended period when the entire system is not fully operational due to the
electrical draw of the system components.
5.
OFF GRID SYSTEMS: Do not connect the Lithium Batteries until the entire system is ready to turn on and is
fully operational.
4.4
Final Connection of the Installation
Final installation and operation guidelines will be dictated by your Electrician and Installer based on the
overall properties of and procedures for the equipment in your installation and any code requirements that
apply to your region. ENSMART technicians and sales staff are available to provide any additional information
on the Lithium Batteries as needed. Please be aware of the potential electrical hazards before interacting
with any and all electrical or mechanical devices. Please take all necessary safety precautions in your projects
and installations.
4.5
Turn off the Unit
If you need to turn off the unit, please push the button for about 6 seconds.
4.6

➢Discharging
•Do not discharge battery below operating voltage.
•Do not discharge battery at rates greater than maximum continuous current.
•Do not operate in conditionsthat will exceed the internal operating temperaturesof the battery.
➢Parameter set up guide in Charger/Inverter
Before commissioning the energy storage system, the appropriate controller and inverter settings must be
programmed per the manufacturer’s recommendations. Consult the manufacturer’s manuals and/or
access technical support (Schneider, Sol-Ark, Victron, SMA, Growatt, Deye).
Although Lithium batteries can perform at very high rates and depths of discharge within a very wide
temperature range, in order to achieve extended life cycles and to comply with the Warranty, the following
guidelines should be followed:
