The surge protector is an important device for preventing overvoltage impact of electrical equipment in buildings. Under the protection of SPD, even if the lightning current of up to tens of kiloamps invades the internal circuit, the surge protector can quickly discharge to the underground g...
The DC circuit breaker refers to the circuit breaker used in the DC power distribution system, which can protect the electrical equipment running on DC power. It is generally suitable for solar photovoltaic power generation and power distribution systems, battery energy storage systems, and n...
How you choose to wire your solar panel is actually important, and it affects the performance of your system and the inverter you will be able to use.
What is Solar Panel in Series?
When you connect the MC4 positive terminal of one solar panel to the MC4 negative terminal of the other s...
PV array DC isolator switch, as the name suggests, is a switch that isolates DC. It is mostly used in photovoltaic power station systems, and is used between high-voltage DC photovoltaic arrays and grid-connected inverters to cut off arcs generated by DC power, avoid dangerous accidents, ...
A waterproof connector is a connector that can be used in an environment with water, and can ensure that the internal mechanical and electrical properties of the connector can be used normally under certain water pressure.

After selecting solar panels, PV cables, inverters and other battery or storage devices, you don’t want to accidentally ruin your entire setup by choosing the wrong combiner box. When choosing a solar string combiner box, the type, size and scope of the project are critical, and what wo...
What is the role of solar DC surge protectors? I think most electrical designers are very clear. Lightning as a serious natural disaster, the occurrence of lightning-caused by transient overvoltage overcurrent is very easy to cause damage to the building’s electrical equipment, espe...
In photovoltaic projects, the choice of copper core cable or aluminum core cable is a long-standing problem. Let’s take a look at their differences and advantages.
The difference between copper core and aluminum core
1. The colors of the two cores are different.
2. The aluminum...
