You can confidently purchase customized solar surge protection from us. We eagerly anticipate working with you. If you wish to learn more, please consult us now, and we will promptly respond to you! China CNKA has successfully developed and produced a variety of industrial electrical products, including circuit breakers (MCB, RCBO, RCCB, ELCB, etc.), fuses, control units, distribution boxes, and AC contactors.
China suppliers CNKA's
latest solar surge protection can prevent lightning surge voltage in
photovoltaic power supply systems. It requires parallel installation on the DC
network to be protected, offering both common and differential mode protection.
It is recommended to install surge protection devices at both ends of the DC
power line, specifically on the solar panel side and the inverter converter
side. Especially in scenarios where the wiring is long and the external
environment is unstable, it is essential to use high-energy power overvoltage
(MOV) with specific thermal isolation switches and related fault indicators.

CNKA solar surge protection FAQ
Q: How long is the
product guarantee?
A: We provide an 18-month warranty and have a dedicated
department responsible for ensuring the quality of our products. Every single
product undergoes 100% inspection to ensure its quality.
Q: What is a PV breaker
in a solar system?
A: Photovoltaic (PV) systems harness the energy of the sun
and convert it into electricity, which is then fed into the electric grid. In
the balance of system (BOS), DC circuit breakers safeguard the wiring that
links the PV modules to the combiner or inverter, acting as both a protective
measure and a means of disconnecting the current flow.
Q: What is a DC circuit
breaker?
A: CNKA DC circuit breakers are designed to safeguard DC-powered
electrical appliances and incorporate supplementary measures to extinguish
arcs. These breakers are a novel technology for most homeowners, as the
majority of household devices operate on AC power and require AC circuit
breakers.
