Every roof in a residential area is different from the one. There are various factors affecting any residential roof — orientation, angle of inclination, shading, inverter inputs, and its voltage range. That’s why a typical, standard, simple combiner box proved to be a compromise. In contrast, the HUYU Combiner Box is provided as an individual-designed item. Its design depends on the number of strings, voltage of the system, and requirements of the inverter of the specific installation.
What a Residential Combiner Box Has to Get Right
The task of the combiner box is to provide the DC strings from the roofs together in one place and at the same time perform three functions. First of all, safe isolation is being performed. Each unit has already been pre-wired with exceptional DC isolators which provide the ability to isolate the array for the purposes of service or emergencies. Secondly, comes surge protection. Surge protective devices (SPD) have been wired in, and therefore induced surges from the lightning or switching cannot pass through to the inverter. The last task of the combiner box is measurement since the enclosure is compatible with smart systems used for energy flow display in homes. The system allows the homeowner to monitor the amount of energy produced by solar panels in real time, having been provided with necessary information through one interface instead of the monthly bill. The enclosure of the device maintains its working parameters outdoors, being waterproof.
HUYU Electric has been manufacturing low-voltage electrical products since 1989 and currently exports them to more than 100 countries of the world as a result of its modernized production facility occupying the territory of approx. 64,738 m² and being equipped according to TUV, KEMA, UL, CE, and CB standards. If you are a homeowner who is planning to upgrade your combiner box to a custom one provided with the above mentioned features, please note that you are entitled to use a combiner box model manufactured specially according to the specifications of your roof. At the same time if you are a solar installer or an authorized distributor, you may expect that you will receive help concerning OEM and ODM support from one and the same company. Just tell us how many strings you have, what voltage your device features and what inverter you are operating with, and we shall send you our response.
