System Design
System Design is the process of defining the architecture, components, modules, interfaces and load data for a
system to satisfy specified requirements.
For a solar energy system, these components are the PV modules, inverter/charge controller & batteries, as
well as the different interfaces of those components.
Battery Operation
There are several factors that affect the operation of the battery that could impact its ability to deliver capacity
and life expectancy.
Storage
Battery Module shall be stored in original packaging, in a clean, level, dry, cool location indoors.
Recommended storage temperature is 77°F / 25°C
The battery can be stored in the range of -4°F to +113°F / -20°C to +45°C but it requires an inspection* and
recharge** every three months (max charging current is 0.1C).
Max SoC storage % is 50%.
*Inspection parameters –identify the State of Charge (SOC), look for any alarms and address accordingly, look for physical
damage to the Battery Module. **Charge at 0.1C and not more than 50% SOC. If shipped by sea, you must refer to the
UN38.3 standard, if by road, refer to the local codes.
Temperature
Many chemical reactions are affected by temperature, and this is true of the reaction that occurs in a storage
battery.
The chemical reaction of a Li-Ion is slowed down by a lowering of the electrolyte temperature that results in
less capacity.
A battery that will deliver 100% of rated capacity at 77°F /25°C will only deliver approximately 75% of rated
capacity at +50°F / +10°C
At temperatures down to +19.4°F /+7°C the charge current may be limited to 0.1C depending on other factors,
however at temperatures below +19.4°F /-7°C charging is restricted by the BMS.
As part of the Performance Warranty, Charge and Discharge shall be in the range +68°F to +77°F +20°C to +25°C
Any usage outside this range is not covered by Performance Warranty.
Depth of Discharge (DoD)
Depth of discharge is a function of design. The deeper the discharge per cycle, the shorter the life of the
battery. A cycle is a discharge and its subsequent recharge regardless of depth of discharge.
Charging
Most battery capacity/life issues can be traced to improper charging. Improper charging settings may lead to an
overcharging or undercharging condition.
Warranty
Although the BMS of the battery allows a wide range of use, both in terms of temperature and charging
currents, this should not be construed as an implicit authorization to use the battery at these levels.
For the purposes of the Performance Warranty, it is mandatory that the battery is used within the range of
temperature and charge/discharge current, and Depth of Discharge indicated in the Performance Warranty.
Warranties only apply to batteries connected via BMS line to an approved inverter.
Any other use, even if permitted by the BMS ranges, is not covered by the Performance Warranty.
