POWER EXPANSION OPTIONS
Adding Batteries to the System
For extended operating time, additional batteries may be added in parallel using the Battery
Terminals located above the wheels. It is recommended to connect 12V AGM batteries with
the same capacity as the internal battery (26 Ah) into the system for long-term use. Connecting
flooded, GEL batteries can, over time, result in uneven charge and discharge between the internal
and external batteries, a battery damaging condition. You may temporarily connect flooded, GEL
batteries to the Solar e Power Case for discharge purposes only. Different battery types require
different charging conditions. The charging systems are designed to charge AGM batteries only. It
is important that you only connect same voltage (12V) batteries to the DC terminals. Reverse polarity
connections can cause an explosion. Connecting external batteries to the Solar e Power Case in
series could cause damage to the system and void the warranty. It is recommended that adding
batteries be performed by a qualified person. If in doubt, a user-provided voltmeter may be needed
to verify voltage and polarity of external batteries to be connected to Solar e Power Case.
CAUTION—External Battery:
• When adding batteries to the system for long-term use, you must use 12V AGM batteries.
Using different construction or chemistry batteries can damage components.
• Total internal and external amp hour rating should not exceed 104 amp hours.
• It is recommended to use at least 10 AWG cable or larger to connect additional batteries
to the Solar e Power Case when drawing full power from the Inverter. Heavy cables reduce
voltage loss in the cables.
External Battery Connection Procedure
1. Locate the Battery Terminals. Batteries must only be connected in parallel.
2. Loosen the Battery Terminal covers and connect the batteries using either ring terminals or
jumper cable clamps. Make sure the connection is secure.
3. With a voltmeter, verify that the battery voltage is correct at the terminals.
4. Turn ON the LCD Display button and observe the combined battery voltage.
CAUTION—Battery Discharge:
The LCD display shows the combined voltage of external and internal battery system. It is important
to monitor the external battery voltage to prevent battery over-discharge.
MAINTENANCE
Maintaining the Solar e Power Case in good operating condition is relatively simple. Charge the
battery until full as often as possible and keep all surfaces free of dust and dirt.
Cleaning
With the Solar e Power Case disconnected from all electrical cords and the fans OFF, you may
carefully vacuum the vents to remove dust.
