75 DC to DC Voltage Converters & Dimmers by Solar Converters

75 DC to DC Voltage Converters & Dimmers by Solar Converters

The items on this page allow you to change voltage in a number

of ways.

By Solar Converters.

The Battery Equalizers (EQ) will allow you to tap a lower voltage

from a higher voltage battery bank to operate lower voltage loads.

It will also allow you to charge a higher voltage battery bank

with a lower voltage charging source.

When using an EQ unit, the load voltage will move up and down

along with the battery bank voltage.

For a fixed/regulated load voltage you would need to use

either a CV or PPT unit, depending on the relationship between

the load voltage and the battery bank voltage.

The Constant Voltage (CV) drivers will allow you to take a lower

voltage battery bank (within its input voltage range) and output a

fixed higher voltage within its amperage limits.

The Modified Power Point Tracking (PPT) unit allows you to

take a higher voltage input (within its input voltage range) and

output a fixed lower voltage within its amperage range.

Everything priced on this page is in-stock, we ship

Monday through Saturday.

DC 2:1 Battery Equalizer

These battery equalizers, EQ units, allow you to tap a lower

voltage off of a higher voltage battery bank.

The EQ piggy-backs the battery bank and equalizes (balances)

out the batteries.

For example, you may want to pull 12 volts off of a 24 volt battery

bank.

You would run your 12 volt loads off of 12 volts worth of batteries.

The EQ unit would pass power from the higher state of charge

batteries to to lower state of charge batteries to balance out the

bank.

This will allow you to draw the lower voltage, within the EQ unit's

amperage rating from your bank.

Please note that there is some momentary surge available, to start

a motor.

The surge capability is based on the size of the battery bank, more

storage capacity, the higher the surge amperage.

The battery bank acts as a buffer for the EQ unit.

You can also charge a higher voltage battery bank from a lower

voltage charging source.

An example would be to use a nominal 12 volt charging source

connected to a 12 volt section of the battery bank.

The EQ unit will start to balance out the battery bank.

Efficiency is greater than 95%.

The 2 amp model has a plastic housing.

The larger models include a NEMA 4 weatherproof enclosure.

Dimensions: 4.5" by 2.5" by 2".

These units are made in Canada by Solar Converters.

If you have any questions about these equalizers, please call us

at (562) 423-4879.

These are NOT designed to be placed between a photovoltaic module

and a charge contoller. The open circuit voltage of the module will

damage the converter.

When using a PPT unit with a load, like a pump or refrigerator

that has a starting amperage which may exceed the amp rating

on you unit we suggest putting a battery in-line (parallel) between the

PPT unit and your load.

The battery will act as a buffer when your load draws high amps

on start up. Once the load starts, the PPT unit will charge the

booster battery and continue to supply power to your load.
