500W Off-Grid True Sine Wave Solar Inverter ISI-501 Series

Introduction:

MEAN WELL introduced 500W DC/AC true sine wave inverter with MPPT (Maximum Power Point Tracking) solar charger~ ISI-501 series. This off-grid solar inverter can be constructed as an energy-saving power station by only adding external lead-acid batteries and solar panels. Through the built-in MPPT solar charger, “free energy” from the sun can be stored into the battery bank by solar panels and then transformed to AC output via its inverter stage, which can conserve the energy consumption. ISI-501 series can provide 500W rated power continuously (450W for 12VDC) for all kinds of electric devices. Peak load capability includes 110% rated power for 1 minute and high surge power up to 200% rated value for 30 utility cycles.

Digitally controlled by microprocessor and designed by high frequency topology, ISI-501 is light weight and possesses up to 88% of high efficiency. The output voltage and frequency can be flexibly adjusted through the front panel according to the demands. These power inverters are equipped with complete protections, include input reverse polarity, BAT low alarm, BAT low shutdown, BAT over voltage for the input side and protections of short circuit, inverter overload, over temperature for the output side. Other standard functions include remote ON/OFF control, LED indicator, BAT low relay contact signal…etc. The design of ISI-501 series comply with global certificates per CE and FCC, which are suitable for powering all kinds of lighting fixtures, household appliances, and portable equipments in the remote mountains, islands, desert areas, or caravans that the utility supply can’t be reached but the solar panels can be constructed.
