Solar energy

is heating up

Interest in renewable energy sources has never been

greater, and the fastest growing of these new green

technologies is the use of photovoltaic (PV) panels

(modules) to generate power from the sun. PV modules

directly convert the sun’s light into electricity, providing

power during daylight hours. PV systems are being

installed on virtually every type of building, resulting in

a growing need for products to meet the requirements

of these systems.

Eaton’s solar combiner boxes

Solar photovoltaic (PV) installations convert sunlight

into electricity, providing clean, renewable energy.

Solar PV systems contain many separate DC source

circuits that must be combined into a single circuit

prior to inversion into clean, usable AC power for

the electric grid.

Eaton is proud to offer a line of solar combiner boxes that provides customers with a high-quality product good enough to bear the Eaton brand.

Solar combiner boxes aggregate the many DC source circuits present in a solar PV system, and provide the overcurrent protection requirements of the National Electrical Code.T

Containing input fuse holders for source protection, the load sides of the fuse holders are connected together on a common bus that contains the output lugs, allowing multiple circuits to be combined into one outgoing circuit.

Eaton’s combiner boxes are available in two styles—source combiners and array combiners. Source combiners are located closer to the source, or the solar panels. They have smaller input fuse holders and lower output currents.

Array combiners (sometimes referred to as re-combiners) are found in larger installations. They aggregate the outputs from several source combiners into a single circuit. Array combiners feature larger input fuse holders and higher output currents. With the full selection of inputs and fuse holder ratings, Eaton’s solar combiner boxes allow for the complete management of solar DC circuits. Until now, these products have been available only from companies specializing in the solar market. With Eaton’s recently announced DC photovoltaic switch, this offering gives Eaton customers a one-stop shop for solar PV balance-of-system electrical equipment.
