We design and manufacture the 3Suns Solar Slate, the mounting hardware and copper covers to fully integrate the 3Suns solar slate into any pitched roof.

We then match the 3Suns Solar Slate with the best solar management system in the world, Solar Edge inverters, Solar Edge power optimisers and the new Tesla power Walls for energy storage.

Here you will find details and specification on each of our products.
The SolarEdge products needed are the, highly efficient PV inverters, the power optimizers, the web portal for module-level monitoring and fault detection and SmartPhone Application for anywhere 3Suns Solar Slate system monitoring.

SolarEdge system enables harvesting more solar power from the 3Suns Solar Slatethan other solar system products in the market today.

The Solar Edge system does this by embedding smart electronic power optimisers per group of 50 x 3Suns Solar Slate tiles (400Watts). This is the solar industry leading level of solar system monitoring granularity and its available for free on any Smart Phone or tablet.
The SolarEdge power optimizer is a smart DC/DC converter that communicates with the intelligent invert. The SolarEdge power optimizers increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. Furthermore, the power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring portal for enhanced, cost-effective module-level maintenance. Each power optimizer is equipped with the unique SafeDC™ feature which automatically shuts down modules' DC voltage whenever the inverter or grid power is shut down.

The Solar Edge Power Optimisers allow for flexible installation design with multiple orientations, tilts. This means it is cost effective to put the 3Suns Solar Slate on ever roof face, even those that are facing away from the sun.

When working with SolarEdge Inverters, SolarEdge power optimizers automatically maintain a fixed string voltage, allowing installers even greater flexibility with longer strings and strings of different lengths in order to design optimal PV systems. Alternatively, the new independent optimization (IndOP™) technology allows power optimizers to be installed without the need for additional interface hardware and to operate directly with any inverter. The SolarEdge power optimizers are compatible with c-Si and thin-film modules and have a 25 year warranty.
The SolarEdge DC-AC PV inverter is specifically designed to work with the SolarEdge power optimizers. Because MPPT and voltage management are handled separately for each module by the power optimizer, the inverter is only responsible for DC to AC inversion. Consequently, it is a less complicated, more cost effective, more reliable solar inverter with a standard 12 year warranty, extendable to 20 or 25 years. The fixed string voltage ensures operation at the highest efficiency at all times (>97% weighted efficiency) independent of string length and temperature.
The SolarEdge PV Monitoring Portal is a web-based application that provides module-level, string-level and system-wide monitoring. The solar monitoring software provides enhanced maintenance of PV systems and yield assurance. The portal automatically provides alerts for accurate and immediate fault detection, localized on a virtual site map for on-site and remote troubleshooting at the module level. Module performance is communicated across existing power lines, so no extra wiring is required.

About Us

The idea for 3Suns commenced  in December 2013 after a mid century modernist architectural home came up for sale in Switzerland. It was built in 1967 with Eternit cement fibre roof tiles and was in need of a new solar roof...
