Heat Pump

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. Versatile applications Domestic hot water (homes, flats, guesthouses) Underfloor heating (low-temp circuits) Pools & spas (extend your swimming season) Small commercial use (offices, gyms, salons) Smart control & connectivity Wi-Fi & Bluetooth app control Live energy tracking (see PV vs grid contribution) Timers for low-tariff windows and comfort schedules Key specs  Capacity: 200 L Type: Solar air-source heat pump (hybrid AC/DC) Efficiency: COP up to ~4.2 (≈420%) Controller: Built-in solar MPPT (≈99.8% tracking) Power modes: Solar direct (day), Grid assist (night/low sun) Safety: PV surge protection, RCD monitoring, over-current/over-voltage Connectivity: Wi-Fi / Bluetooth; app monitoring & control What’s in the box Deye 200 L Solar Air-Source Water Heater (AC/DC) Integrated MPPT solar controller User manual & quick-start guide Installation notes (recommend) Professional installation required by a qualified plumber/electrician. Position for good airflow and sun exposure; follow PV string/voltage guidelines. Add isolators, drip tray & safety valves per local regulations. 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.

DEYE 300L Solar Air-Source Water Heater (AC/DC) Bigger tank. Same ultra-efficient, solar-first heating. Top benefits Up to 4.2× efficiency (COP ≈ 4.2) – ~4.2 kW heat from ~1 kW electricity Solar-first, grid-assist – runs directly from PV by day; seamless AC backup at night/low sun Smart control – Wi-Fi/Bluetooth app, schedules, weather-adaptive heating, grid power limiter Why this heater? Large 300 L capacity – great for bigger families, guesthouses, or light commercial use. Real energy savings – extracts free heat from ambient air + sun to slash electricity costs. Daytime independence – operates on DC solar with no inverter or batteries required. Always-on hot water – auto-switches to grid AC when needed, with solar as priority. Intelligent comfort – weather compensation adjusts target temps to avoid wasted energy. Safer by design – PV lightning protection, residual-current monitoring, over-current/over-voltage protection. Smart control & monitoring Deye Smart App (Wi-Fi/Bluetooth): set temps, view power usage, schedule heating. Grid AC Power Limiter: one-touch cap on grid draw to manage costs. Versatile applications Domestic hot water (homes, apartments, B&Bs) Underfloor heating (low-temp circuits) Pools & spas (extend the swim season) Offices, gyms, salons (light commercial) Key specs (quick view) Capacity: 300 L Type: Solar air-source heat pump (hybrid AC/DC) Efficiency: COP up to ~4.2 Power modes: Solar direct (day), Grid assist (night/low sun) Controls: App (Wi-Fi/Bluetooth), timers, weather compensation, AC limiter Safety: PV surge protection, residual current monitoring, over-current/over-voltage   What’s in the box Deye 300 L Solar Air-Source Water Heater (AC/DC) Integrated solar control electronics User manual & quick-start guide Installation notes (recommend) Professional install by qualified plumber/electrician. Site for good airflow and PV exposure; include isolators and safety valves per local regs. Confirm PV string sizing and cable protection to spec.   Mini-FAQ Q: Does it work during load-shedding?A: Yes. It can run off PV during the day; at night/low sun it uses limited AC as backup. Q: Do I need an inverter or batteries?A: No. It’s designed to connect directly to solar PV and can use grid AC when needed. Q: Is 300 L right for me?A: Choose 300 L for 4–7+ users, guest suites, or light commercial. For 2–4 users, consider the 200 L model.
