The KF4JVI Solar Powered Repeater
145.330 Neg. Offset with a PL Tone of 91.5 Hz
The KF4JVI Repeater is an open repeater
however SERA Repeater Association has requested that all repeaters in the
SE USA be tone controlled, thus the
frequency is 145.330 with a minus offset and PL tone of 91.5 Hz.

Our Solar Panels Array
using 4 panels
to produce approx. 10 amps DC at 12.6 Volts under full sun.
This is showing the wiring
and the junction box.
Proper grounding of the equipment allows it to live through electrical storms
Description of Our Solar Panels Array
Four Semiens M55 Solar
Panels are connected in Parallel.
Each Panel Produces 55 watts of 12.6 volt electricity at 3.5 amperage.
Connected in Parallel, the four panels produce a maximum
electrical charging output of 12.6 volts at 14 amps.
Remember that this is 1998 technology.
If on an average of only
four hours of direct sunlight per day,
this will give us approximately 56 amp hours of battery charge daily.
All of the pictures below are 200K or larger to provide very fine detail.
Ananda Power Technologies Solar Controller.
The solar controller automatically regulates the charge to the battery
This provides an automatic float charging or disconnect of the
Solar panels when the battery bank reaches full charging capacity.
The Controller Box also provides the circuit breakers to isolate the
Radio, Batteries, and solar panels.
Below is the
controller panel for the battery pack.
Photo below is the fusing
for the battery pack.
Below that is a sub controller for aux power if necessary
The Battery Bank
The Battery Bank consist of
four Deka Gel Packs
12.6 volt at 220 amp hour per battery.
These batteries are
all connected in parallel.
This provides about 900 amp hours of electrical storage at 12.6 volts.
This storage capacity
should power the KF4JVI radio repeater for approximately
8 days with out any additional charging form the solar panels.
is mounted at the top a
35 foot telephone pole.
Our antenna is made by Cellways Inc.

Overall View of the
The Green box in the photos below is an emergency battery charger should we need
it while preforming work on the site. So far we have not used it as the panels have done
their job very well.
The Actual Layout of the equipment of this repeater site.
The equipment sits atop of the
duplexer which is housed
in the lower part of the cabinet.
The battery bank is in front of the duplexers and are enclosed in a seperate cabinate.
The KF4JVI Repeater
equipment consist of the following equipment:
Yaseu - Vertex 2 meter repeater
S-Com V7 Repeater Controller
2 pair duplexers ~ 2 tx and 2 rx
4 batteries at 220 amp hours sealed gel packs.
Solar Controller assembly
Overkill on lightning protection
Green Box is Backup / standby power if necessary - so far not required.
