M8145 • Inverter UPS Pure Sinewave 3.6KVA 24V Input
They are designed to be permanently connected to 240V mains grid power, a solar array and suitably sized battery bank. Under normal mains conditions the load is direct fed, under mains failure the inverter, powered from the battery bank, takes over and supplies the load. Switch over from mains to inverter is via the automatic bypass switch which switches within 8ms ensuring a seamless changeover.
The control panel with LCD provides adjustments for mains output voltage, output frequency. Essential battery parameters can be monitored including capacity remaining, current and voltage. The control panel may be removed and located remotely via Cat5 UTP cable up to 50m from the main unit.
Inverter: Produces a clean and smooth sine wave AC output with very low distortion (<3%) and precise frequency control. The soft-start circuitry and large surge capacity enable the units to power heavy inductive loads. The overload and short circuit protection system ensures safe and reliable operation. An internal bypass switch enables the unit to operate as an automatic backup power supply whilst connected to the mains grid. When connected to mains power the unit functions as a battery charger, keeping the backup cells topped up. If mains power fails, the unit automatically switches to inverter mode and continues to power the connected devices. No user intervention is required and the bypass switch will activate within 8ms, ensuring minimal power disruption.
Battery Charger: Charges and maintains either gel cells or lead-acid battery banks up to 500Ah. The microprocessor circuitry ensures batteries are charged to their optimum capacity using a 3 step process. This maximises battery capacity and life. Charging parameters are user-configurable depending on battery size. This allows the charger to be matched precisely to the kinds of batteries being employed.
Solar Regulator: The internal solar regulator allows direct connection of solar panels, integrating them into a remote power system. The connected batteries are charged and maintained automatically from the solar panels. If the unit is connected to mains power or a generator, battery charge is automatically balanced between mains and solar panels.
