What is a DC combiner box?

Our DC combiner boxes offer users the possibility to integrate short-circuit and overvoltage protection, as well string monitoring solutions (I,V, T and SPD and switch isolator status), for PV systems using central inverters with PV panels in trackers and fix tilt systems.

Can you install a PV system without a combiner box?

“We have seen problems on installations without combiner boxes, most often in emerging markets where installers/customers combine the PV source circuits in some other way, typically to bring costs down,” Hixson says.

What is a combiner box?

Combiner boxes are designed to accommodate the inherent scalability and flexibility of solar installations. As the number of panels or inverters changes, the combiner box can be easily configured or upgraded to meet changing system requirements.

Japan solar pv equipment

The Japanese government is seeking to expand solar power by enacting subsidies and a (FIT). In December 2008, the announced a goal of 70% of new homes having solar power installed, and would be spending $145 million in the first quarter of 2009 to encourage home solar power. The government enacted a feed-in tariff in November 2009 that requires utilities to purchase excess solar power sent to the grid by homes. [pdf]
