Bidirectional voltage regulator for self-consumption VR EQX: Solution for mains voltage problems in photovoltaic installations Salicru’s VR EQX range of voltage regulators for mains-connected photovoltaic installations prevent outages due to over/under voltage in the power line. Most regulations governing this type of system’s connection to the grid require solar inverters to shut down if their voltage exceeds certain limits. In unstable networks, this causes unwanted stoppages in the photovoltaic installation, with the consequent loss of power generation and a decrease in the useful life of solar inverters. Since, in the vast majority of cases, the surplus energy generated is injected into the grid (in return for compensation), traditional unidirectional voltage stabilisers are unsuitable because they can’t carry reverse current. Given that it constitutes a breach of regulations and exposes the loads to serious danger, manipulating the inverter is not a viable solution to the problem either. These regulators record and manage the grid voltage at all times, responding with quick and precise voltage jumps during the short period of time it may be required for the vast majority of national grids. Applications: The VR EQX range is predominantly designed for grid-connected solar photovoltaic self-consumption installations when the main power line is liable to a certain amount of voltage instability. Regardless of the inverter brand, they ensure the viability of these systems, which are all subject to the same regulation. Advance studies of the electrical network are generally difficult to carry out for various reasons, making these bidirectional voltage regulators indispensable for companies dedicated to offering these types of installati
