Aiming to expand the portfolio of solutions for the solar sector, CHINT Global launched a line of solutions for the Brazilian market string box. Focusing on protecting residential photovoltaic systems, the product offers safety and protection for both direct current and alternating current.
The advantages of the company's equipment include standardization of DC and AC versions, robustness and durability. The string boxes have a uniform design standard, combined with an IP65 protection rating, ensuring resistance to dust, water and additional anti-UV protection for a longer service life even in more exposed environments.
Furthermore, the manufacturer stated that the solution is easy to install. “The boxes already come with a cable gland included, making it easier to connect cables and ensuring organization,” they emphasized.
Below are other advantages listed by the company:
- Diversity of models: CHINT's string box offers a wide range of direct current configurations, from models with one input and one output to those with three inputs and three outputs, as well as options with four inputs and two outputs. On the alternating current side, single-phase and two-phase models are available in a single box, as well as a three-phase option;
- Compatibility: the boxes are compatible with most inverters on the market, ensuring flexibility and ease of integration into any photovoltaic system.
Another point emphasized by the company is that the product offers 1500 VDC terminals for a safe and efficient connection, a robust disconnector switch designed to operate safely at up to 1500 VDC and standardized solar cables for compatibility and compliance with the highest industry standards.
“The line also has a high quality standard, with certified components and rigorously tested models to ensure reliable performance. CHINT is committed to meeting the needs of customers throughout the country, offering fast delivery of the string box to any region of Brazil,” they concluded.

Essential protections offered by string boxes
Direct Current (DC) Side: Positioned between the modules and the inverter, the string box protects against voltage surges in the photovoltaic inverter, facilitating maintenance and avoiding undue actions with its dedicated disconnector switch.
Alternating Current (AC) Side: Also known as a combiner box, the string box for alternating current offers protection against overcurrents and short circuits, along with a specific DPS to protect against voltage surges in direct current.

An answer
It is yet another alternative for a market that has also been showing consolidated expansion here in Brazil. It is already the second largest in installed capacity, second only to hydroelectric plants, which are unbeatable in the country. The area of protection and compatibility with frequency inversions is a technical requirement of utmost importance and associated with a good IPI degree. All of these are aspects that are often neglected and only valued when problems come to light. Engineer and professor. Specialist in solar projects and electric vehicle charging stations.
