For a motor of any kind you should always use a true sine wave inverter. We suggest a
1000 watt inverter. These are available in the hard wire or GFCI outlet type built into the
inverter. The battery bank can be two Type 31, 130 amp-hour marine batteries, however
you will get a better life from deep cycle batteries. Three will work with this system and give a
little extra power. However, will take a little longer to fully charge three batteries of this size.
As long as you have 240 amp-hours in battery power you should have no problems running
the lift. Best batteries for this would be the Trojan T-105 or the Trojan L-16 totaling between
240 AH and 400 AH.

In this package:

Three 110 watt solar modules.

One solar module mount with adjustable legs to hold the three modules.

Charge Controller for a 12-volt system.

1000 watt true sine wave inverter.

Inverter to battery disconnect breaker.

To keep your cost down, Items you can get at a local hardware store or a local battery store
such as long wire runs, AC breakers and breaker boxes, batteries and battery cables are
not included with this system.

This solar boat dock system will have enough power to run a small light or radio along with
the use of the boatlift.
