2.0 INSTALLATION
Pre-Installation (continued)

Batteries:

• The battery voltage MUST match the voltage requirements of the inverter. To determine the
correct voltage for the system, check the last two digits on the inverter’s model number. For
example, the DR1512 is a 12 volt inverter and requires a 12 VDC battery system. The
DR2424 is a 24 volt inverter and requires a 24 VDC battery system.
• Locate the batteries in an accessible location. Two feet clearance above the batteries is
recommended for access to the battery caps. They should be located as close to the inverter
as possible without limiting access to the inverter’s disconnects. Install the batteries to the left
of a wall mounted inverter for easy access to the DC side of the inverter and shorter cable
runs.
• For safety and to limit access to the batteries, a lockable, ventilated, battery enclosure or
dedicated room should be used. If an enclosure is used, it should be vented to the outside
via a one inch vent pipe located at the top of the enclosure. Install an intake vent at the
bottom of the enclosure to promote air circulation. These vents exhaust explosive hydrogen
gases and must not be overlooked when designing an enclosure.
• The enclosure should be made of an acid resistant material or have a finish that resists acid
to prevent corrosion. It should be capable of holding the electrolyte from at least one battery
should a leak occur.
• Place a layer of baking soda on the shelves to neutralize any acid that may be spilled in the
future (lead-acid batteries only).
• Enclosures located outside must be rainproof and screened to prevent access by rodents or
insects.
The battery enclosure should provide a fairly stable temperature for the batteries. If it is installed
in a cold environment, insulation should be used to protect the batteries from the cold. The insulation
also provides a more consistent temperature and better system performance.
The battery enclosure should not be installed in direct sunlight where the summer sun can
overheat the batteries. Locate the enclosure where it will be protected from the afternoon sun and
provide vents in the top and bottom of the enclosure to provide air flow. High battery
temperatures greatly shortens the life of the batteries.
