PHB Solar launches the first 127 V single-phase string inverter in Brazil

PHB Solar launched this Monday (7) the first 127 V single-phase string solar inverter in Brazil, the PHB2900D-NS. According to the company, the equipment has two MPPTs (Maximum Power Point Tracking) that allow for more flexibility in photovoltaic projects.

Furthermore, the solar inverter has integrated Wi-Fi, an LCD screen in Portuguese and is easy to install. Also according to PHB Solar, after the purchase, the consumer can count on the company's full after-sales support.

“We were the first company to have an inverter certified by Inmetro. We developed our own software to adapt our inverters to the voltages stipulated by PRODIST in a simple way. Furthermore, we have the largest line of 220 V three-phase inverters in Brazil. And today we launch this 127 V single-phase inverter to serve our customers with quality and technology”, highlighted Ildo Bet, director of PHB Solar.

According to the company, the solution meets a demand in the Brazilian photovoltaic market, as many consumer units in the country, such as those located in the states of Minas Gerais, Rio de Janeiro and Espirito Santo, are served using single-phase 127 V networks.

Since all single-phase string inverters are designed to work at 220V, the designer usually uses a step-down transformer. Another possibility is to request an increase in load to access a two-phase network.

However, these alternatives have disadvantages. Among them, the increase in the minimum monthly tariff from 30 kWh to 50 kWh, expenses involved with adapting the standard. Furthermore, the use of the transformer increases the initial cost and losses in the system.
