Parameter settings

Lead-acid batteries can be replaced by lithium battery of NPFC series if power is matched. Table 3-1
is new parameter settings of power plant for lithium battery.
Table 3-1 Parameter Settings of Power Plant for NPFC Series Batteries
No. Parameters
1 Float charge voltage
2 Equalization charge voltage
3 Standard charge current
4 Charge current limitation
5 Equalization charge interval
6 Equalization charge duration
7 Condition to equalization charge
8 Condition to float charge
9 Recovered LLVD voltage

11 BLVD
12 Temperature compensation for float charge
13 Temperature compensation for equalization charge
Note:
1.Equalization charge is requested to switch off for NPFC series batteries.
2.Rectifier parameter shall be set according to specific site requirement based on battery units used.
3.If the battery connected more than 2 in parallel, the max. charge current recommend 0.5C.

Storage and Installation
Chapter Four/04
Storage
■ Storage temperature range: 0°C to 40°C.
■ Storage battery should be at 50%-80%SOC.
■ Recharge charge before using to recover capacity loss of self-discharge during storage and
transport.
■ Recharge battery during long-term storage for self-discharge. Recharge program as follow table:
Storage temperature Recharge interval
0°C-30°C Every 6 months
30°C-40°C Every 3 months
■ Storage battery over 40°C or under 0°C will reduce battery life,
■ Storage battery in dry and low temperature, well ventilated place
■ Battery performance degradation after long-term storage, please shorten shelf time as possible
as you can.

Installation

Unboxing & Inspection
■ Please study this manual before installation.
■ Please inspect the package before unboxing, if any destroy with appearance, contact with the
supplier as soon as possible.
■ This device shall be installed and operated by professionals.
Preparation for Installation
■ Batteries shall not be placed in direct sunshine or close to heat source.
■ Batteries shall be installed in place with good ventilation to assure enough heat dissipation.
■ Batteries shall be placed in are with clean ambient and low humidity.
