link system monitor
Link 10 System Monitor

Batteries/Link System monitors
AC & DC METERS
Link 10 Single Bank Monitor

Our affordable battery bank monitors give you all the information you need to manage your power system. The Link 10 monitors a single bank, while the Link 20 can monitor two separate battery banks. Both have an easy-to read LED bar graph showing battery state-of-charge at a glance.
FERRIS POWER FACT:
Electricity only seems "mysterious" because we can't see it, but with the proper monitoring system, electricity and its effects become visible.
Today's monitors provide all of the vital information you need to know about your independent power system.

Displays include:
• DC Amps - current flow in or out of the batteries

• DC volts - voltage of your batteries
• Amp-hours - energy removed from the batteries
• Time - how long until the battery is discharged

We offer many products and packages for your Link Monitor. Be sure to order the required cable and fuses for installation. We’ll even pre-program your monitor to make your installation a breeze. See below.

Batteries
MK AGM & GEL Batteries
AGM & GEL BATTERIES

MK Batteries
The heart of any power system is the battery bank and its ability to store & deliver power as needed. Today’s popular lead acid batteries are the AGM (absorbed glass matt), GEL and flooded batteries. Many users are turning to the MK AGM Batteries due to the “no maintenance” and long life aspects of these batteries. No maintenance means, no water level checks, no spillage, no gassing and as a result, no corrosion on the battery terminals or cables. Since they are totally sealed, you can install these batteries on their side without any fear of spillage and they don’t need a battery box.

The MK AGM & GEL Batteries are built by East Penn Mfg., the same company that built the original Prevailer Gel Battery that set the standard for the industry. Few compare to these standards. MK AGM & GEL Batteries have combined deep cycle and starting battery properties that serve perfectly in both applications. Compare these features to other batteries and you’ll understand why MK AGM’s & GEL’s are quickly becoming the number one choice.

5 Important reasons to buy your AGM and Gel Batteries from Hamilton Ferris Co.
1) Our prices are great! Check and Compare!
2) You choose, AGM or GEL - The cost is the same!
3) * FREE Nationwide Delivery. You pay a small handling fee.
4) If you are outside of MA, you don’t pay any sales tax.
5) Nationwide Warranty - If you should have a problem, we’ll fix it fast!

METERS, TRANSFER SWITCHES &
TRANSFORMERS

FERRIS Panel Meters
These handy, affordable meters allow you to keep track of the charging rate of any power source, the consumption rate of any appliance, and the voltage of DC battery banks, AC shorepower, or gen-set.

Auto Transfer Switch
This switch AUTOMATICALLY transfers the load from your inverter to "line power" when you start your generator or plug into "shore power". These same switches are used and required by law, for home standby generators.

 

Trace Step-Up/Step-Down
Trace Step-Up/Step-Down Transformers
This high-efficiency, heavy-duty transformer can be used for voltage step-up from 120 to 240 V AC or step-down from 240 to 120 V AC. Step-up voltage to use 240 V AC appliances from a 120 V AC circuit, such as for deep wellpumps.
