APV Series Smart Solar PV Combiner Box
General
In a large photovoltaic power generation system, it is necessary to connect numerous photovoltaic battery packs in the series and parallel combination to reach the required voltage and current value in order to maximize the power generation efficiency. The main purpose of APV series smart photovoltaic combiner box is to conduct the first-stage confluence for the photocell array input which is used to reduce the wiring between photovoltaic battery array and inverter, optimize the system structure, improve the reliability and maintainability.
The APV series smart photovoltaic combiner box not only provides lightning protection confluence function, but also provides the function of photocell current measurement, detection for solar panel operation in the photocell array, battery voltage after confluence, the total confluence power, the branch power, acquisition of combiner lightning protector state, acquisition of DC breaker state, the relay contact output, the interface with the air speed, temperature sensor and irradiator etc. available for customer’s option.
The device of standard configuration has a RS485 interface which can upload the picked-up data and equipment state to the monitoring system.
