Product Description

Details

Converts photovoltaic (PV) solar power into electrical energy that is compatible with powering an existing standard AC geyser installation. SolarHotty has a patented innovation to allow the standard AC thermostat to utilize the supplied voltage (AC or DC) [Patent pending: 2017/00889 and GB1610106.5]. The electrical wiring interface to the geyser is the only change you will need to make to the existing installation.

SolarHotty Features

  • 200-240V 50/60Hz Mains AC Supply.
  • No battery or inverter needed.
  • Works on a standard geyser AC thermostat.
  • Automatic switching between AC and PV DC sources depending on solar level.
  • PV supply from one or more series-connected solar panels (Refer to Images above).
  • Automatic maximisation of PV power using inbuilt.
  • Maximum Power Point Tracker (MPPT).
  • Rugged steel housing PV DC supply short-circuit protection against geyser element load failure.
  • LED indicators for fault indication and PV supply indication.
  • Protection against PV panel reverse-polarity.
  • Easy mounting to roof beam provided by pre-drilled bracket.
  • Zero configuration installation.
  • Continual monitoring of health and integrity with failsafe operation.

LED Legend
Green LED (POWER SOURCE)

  • Fast-flashing (100ms on / 100ms off): performing self-tests.
  • Slow-flashing (500ms on / 500ms off): supplying AC to the geyser element.
  • On: supplying PV DC to the geyser element.

Red LED (FAULT)

  • Flashing (500ms on / 500ms off): PV panels connected in reverse polarity.
  • On: Fault – either element short circuit or other faults.
  • Off: No detectable fault.
