Top benefits

• Up to 4.2× efficiency (COP ≈ 420%) – ~4.2 kW heat from ~1 kW electricity

• Solar-first, grid-assist – works without an inverter or batteries

• Smart control – Built-in MPPT, Wi-Fi/Bluetooth app, timers & power limiter

Why this heater?

• Massive energy savings – Harvests ~3.2 kW from ambient air + sun for every ~1 kW drawn.

• True daytime independence – Runs directly from PV; no inverter or battery required.

• Always-on hot water – Seamless AC assist at night or in low-sun conditions.

• Built-in intelligence – Integrated MPPT (≈99.8% tracking), one-touch AC limiter, real-time power monitoring, and scheduling.

• All-season performance – Designed to heat reliably in both low and high ambient temperatures.

• Safer by design – PV lightning protection, residual current monitoring, over-current & over-voltage protection.

Mini-FAQ

Q: Will it work during load-shedding?
A: Yes—during the day it can run directly from PV. At night or low-sun it can draw limited AC from the grid as needed.

Q: Do I need an inverter or batteries?
A: No inverter/batteries required. It’s designed to connect directly to solar PV and can use grid AC as backup.
