Geyserwise Megawatt Saver (MWS) 100L to 200L SMART Solar Geyser Conversion Kit

Geyserwise Megawatt Saver (MWS) 100L – 200L SMART Solar Geyser Conversion Kit Convert Your Existing Electric Geyser into a Smart Solar Heating System Upgrade your home with the Geyserwise MWS SMART Solar Conversion Kit — a revolutionary, Wi-Fi-enabled system that transforms your standard electric geyser (up to 200L) into a solar-powered, energy-efficient water heating solution. This next-generation plug-and-play kit eliminates the need for complicated plumbing, pumps, or element replacements. Instead, it uses photovoltaic (PV) solar panels to generate electricity and directly power your geyser — with smart automation and full remote control via the Tuya or SmartLife app. Why Choose the Geyserwise MWS Solar Conversion Kit?
