The B-Van is equipped with a 51.2V house battery, an alternator, alternator regulator, 3500W Inverter solar
charger, and 200W of solar panels. These instructions will lay out the components and how to operate and
maintain them.
Must Read Before Operating
• These instructions are for reference only, please refer to the individual product manuals for detailed
instructions and data.
• Do not modify or alter the components in any way.
• Do not connect an external charger to the Lithium Battery.
• Do not alter the solar array in any way.
• Do not connect anything other than the Renogy solar blanket (optional) to the external solar
connection.
• Do not attempt to charge the battery with the following conditions:
o If the voltage difference between the min and max cell voltage is greater than 800mv.
o If the battery total voltage is less than 32V.
o If the max cell reads 8,000mV or similar.
o If the min cell is under 2,000mV.
• When completing service, do not connect or disconnect any 48V DC system components while the
system is ON. Verify the Lithium Battery is OFF and all charging sources:
A. Alternator
B. Shore Power
C. Rooftop Solar – disconnect near battery in the ‘OFF’ position
D. Side Solar

Quick Startup
• It is highly recommended that all charging sources are OFF when powering up and powering down the
lithium system. (See Getting Started and Powering Down – Storage and Service sections)
• The Samkoon battery screen should be the primary screen to gather lithium battery information as it
provides information directly from the battery BMS.
• If the battery reaches 20% SOC, Total Voltage ≥ 50.0V and/or Minimum Cell Voltage ≥3100mV. The
unit will need to start receiving a charge.
• When the unit is depleted below 10% SOC, this can cause the SOC% and voltage
levels to be out of
calibration. Recalibrate the BMS by changing the inverter parameter #9 to 54.4 and charge the unit to
100%
SOC.
• It is imperative to try to recharge the battery to 100% SOC, as this also recalibrates the BMS and balances
cells.
• The 12V Master Disconnect (Main Power) Switch must be in ‘ON’ for the unit to charge with the
Alternator.
• When charging with shore power, do NOT start the vehicle.
