PV Water Heaters
Προβάλλονται όλα - 4 αποτελέσματαSorted by latest
PV water heaters turn daylight straight into hot water, drawing DC power from a photovoltaic panel through an MPPT controller built into the cylinder. Trikkis Energy stocks the Helios Smart range in 80 L, 150 L, 200 L, and 300 L capacities, each able to accept up to 4,000 W of DC input across an MPPT window of 120 V DC to 340 V DC. Solar power takes priority; a single-phase 220 V AC element covers cloudy spells and faster reheating, and the temperature can be set from a phone over Wi-Fi. Warranty runs to 5 years. Every model is in stock, with technical guidance available before you order.
Does it work without sunshine?
Yes. Each cylinder carries a single-phase 220 V AC connection as backup, and the controller switches over automatically when photovoltaic input falls short of the temperature you have set. Priority always goes to DC power first, so the grid only contributes on overcast days or during heavy evening use.
Which capacity suits my household?
As a rough guide, 80 L covers one or two people, 150 L a small family, 200 L a household of four with a bath, and 300 L larger homes or premises with steady demand. Usage pattern matters more than headcount, so a household showering in the evening may want the next size up.
How many panels does one heater need?
Each unit accepts up to 4,000 W of DC input within an MPPT range of 120 V DC to 340 V DC, drawing a maximum of 12.5 A DC. In practice that means a small dedicated string sized to the element rather than a full rooftop array, and our team can confirm the panel count against your roof.
Do I need an inverter or a battery?
Neither. The MPPT controller sits inside the water heater and takes the panel output directly, which is what makes this route cheaper than heating water from a full photovoltaic system. That also keeps the hot water working independently of anything happening on the inverter side.
