Okaya's entry-level Off-Grid Solar PCU, built for small homes, single shops, or remote spots running a few essentials — lights, fans, mobile charging, and a small TV. With Dual Interleaved MPPT (DiM) technology, it's the most budget-friendly way to start solar backup without giving up efficiency.
Ordinary inverters at entry-level pricing usually skip MPPT and use basic PWM, leaving solar energy untapped. Okaya's 925VA uses DiM (MPPT) technology even at this price point, capturing up to 98% of available solar power — efficiency you don't normally get this cheap.
A single 12V battery (100–200Ah) and a PV range of 32–60V, handling 940–1120W of solar panels — typically 2–3 panels depending on wattage.
Yes — true sine wave output, the same clean waveform as grid electricity, safe for TVs, laptops, and small kitchen appliances. Many budget inverters use modified square wave instead, which can cause humming or premature wear in electronics.
Overload, over-temperature, short circuit, mains fuse trip, and PV reverse protection, with audible alarms for grid failure and low battery — a fuller protection set than most entry-level alternatives offer.
36 months, with BIS, ISO, and CE certification.
