Frequently Asked Questions (FAQ)
How long does it take to fully charge the Lithium Battery?
• There are a number of variables surrounding the length of time to fully charge the Lithium Battery.
• The Inverter Boost Charge Voltage (setting #9) should be set to 54.0 most of the time. The system
can be charged utilizing alternator, shore power and/or solar.
• The battery needs to be maintained above 20% SOC, Total Voltage ≥ 50.0V and/or Minimum Cell
Voltage ≥3100mV. When any of the parameters are met, a recharge cycle needs to take place. This
can be completed by either connection to 120VAC 30A source or starting the engine to allow the
engine driven alternator/generator to recharge the battery.
What is my Battery Operation Status?
• The battery contains a battery management system (BMS) that warns
you and protects the battery from over-voltage, under-voltage, over-
current, short circuit, high temperature, low temperature, uneven
temperature, uneven voltage, and insulation fault. At the Battery
Operation Status, you will find a number between 0-3.
0 = Normal (NO faults and all operating values are within normal
range)
1 = Warning – message will clear when the system recovery value is reached
2 = Alarm – requires a battery restart when the system recovery value is reached
3 = Protection – requires a battery restart when the system recovery value is reached
• It is important to note that a lithium battery fault may affect multiple components. By first looking at
the battery monitor screen (Renogy Samkoon), it will help diagnose the root cause of the fault and
allow for the fault to be corrected. Once the battery fault is corrected, all other erroneous faults will be
cleared from alternator regulator. The most common faults are under-voltage, over-voltage and under-
temperature. It is important to know that the severity number of the fault, which is indicated in the
second bubble below the battery is a 1 (warning), 2(alarm), 3(protection). Any condition with the fault
level of 1 or warning is self-recoverable, and will correct itself once the level of the waring is reduced.
