A 5 kVA, 48-volt sine-wave inverter converts DC power (from batteries or solar panels) into a clean, stable AC output suitable for homes or small businesses. The “sine-wave” output ensures minimal harmonic distortion, meaning sensitive appliances (TVs, fridges, computers, air conditioners) run smoothly without noise or overheating. At 48 V input, the inverter works with a battery bank (or solar setup) sized for moderate downtime.
