The SENTRY Solar Charged System
The Sentry gate opener is the first truly solar charged gate opener for the Do It Yourself market. The
system design and the accessories recommended are all Solar Friendly meaning that they require the
least amount of energy possible to perform the job they were designed to do. The solar option allows
you to install the gate opener in remote areas or in applications where you prefer to be solar charged.
Solar charging provides isolation from lightning that might damage the unit via the AC power needed
for the transformer.
The Sentry gate opener is designed to provide enough cycles a day for most installations without
needing more than one solar panel. Care must be taken to ensure the solar panel has full sun
throughout the day; partial sun will give partial results. If no sun is present then a solar system is not
practical no matter how many panels might be installed. Solar Panel must be kept clean and in full
sunlight.
The design of the system must pay particular attention to any accessories that might be added,
use only Solar Friendly accessories to help avoid premature battery failure. For a complete list of
accessories please visit www.sentrygateopener.com.
GATE CYCLES PER DAY SOLAR CHARGED SYSTEM
(Optional Solar Kit PN #520015)
Solar charged systems should not exceed the cycles listed in the chart below. These numbers are
based on a single 5 watt solar panel installation. If additional panels are installed additional cycles will
be available.
Model Type
REGION 1
REGION 2
REGION 3
Sentry 300 S single gate
8 cycles per day
27 cycles per day
50 cycles per day
Sentry 300 D dual gate
5 cycles per day
13 cycles per day
23 cycles per day
Region 1 covers the area of the country receiving the least amount of solar radiation. On average the
amount of charge time is 1.5 hours in region 1, 3 hours in region 2 and 5 hours in region 3.
These are conservative numbers and the Sentry opener should have no problem
performing as stated in the chart above. See Region Map above to determine cycles
that can be expected. These numbers are based on a basic system and adding solar
friendly accessories will not have any great affect on the numbers stated. Using other
accessories can cause premature battery failure. Look for the solar friendly logo when
considering accessories for your gate opener.
