It converts the direct voltage produced by photovoltaic panels into alternating voltage (230V/50Hz) for photovoltaic power plants.
The device is also suitable for powering electrical devices requiring 230V alternating voltage and as an emergency power source it will ensure trouble-free operation of devices requiring continuous power supply, e.g. central heating pumps or alarm and monitoring systems.
KEMOT solar converters are an additional source of electrical energy obtained from solar energy, which in the event of a power failure will support all devices requiring constant power from the grid in your home. Importantly, the device needs a maximum of 6 milliseconds to switch between individual modes.
PV priority mode 1. During the day (sunlight is enough) and the devices are also connected to the network: the photovoltaic cells will power the external device and charge the battery at the same time (the network will be in standby mode during this time). 2. In the evening, the system will power the device from the battery until the low voltage protection is activated; then the system automatically switches to AC and charges the battery to a certain level to provide power in an emergency. The battery will be fully charged by the PV cell when the PV power is restored.
AC priority mode 1. Mains power is available: devices will be mains powered. The solar cells will charge the battery. 2. In case of out-of-range voltage or mains power failure: Connected devices will be powered by battery and photovoltaic cells to maintain power continuity. If the power from the photovoltaic cells is unavailable or insufficient, the connected devices will be powered only by the battery.
Pure sine wave Solar converters from the PROsolar series are suitable for all devices that are extremely sensitive to the slightest changes in the shape of the voltage. Their advantage is a clean sine wave of the output voltage (supplying the load), thanks to which the devices ensure stable operation and prevent the effect of overheating of inductive loads. Together with the battery, it forms a complete 230 VAC guaranteed power supply device.
The solar inverter KEMOT PROsolar-3500 has a solid cover, equipped with a holder that allows it to be hung on a wall, for example in a boiler room or electrical switchboard.
