Energy storage options
Lithium-ion Lithium-ion based battery packs have the added advantage that they have a higher power density than lead, which means they have more available power for the same mass of a lead battery. This advantage, combined with the longer life expectancy and higher rate of depth of discharge (DOD), offering an attractive option for solar lighting applications, resulting in a longer battery lifetime. Our renowned Tier 1 branded cells ensure the highest quality product. In addition, all Lithium-ion battery packs have an integrated Battery Management System (BMS) which monitors the health, charging and discharging of the battery pack. This safeguards the cells so that they are not over
Intelligent luminaire drivers are programmed if required in the factory with complex dimming profiles. Up to 6 combinations of time intervals and light levels are possible. This feature does not require any extra wiring. The period between switching on and switching off is used to activate the preset dimming profile.

Autonomy Days
Solar module
Autonomy Days refers to the number of nights/cycles a luminaire will continue to work without receiving a charge/being charged from the solar panel, due to adverse weather conditions. The number of autonomy days is aligned to the energy storage unit's depth of discharge resulting in sufficient capacity after a night/cycle.
The solar panels are ISO and TÜV certified and carry a 10-year product warranty. Hail- resistant and corrosion-proof. Rated outputs on the panels are 90% minimum for the first 10 years and 80% minimum after 25 years. Panel outputs are designed to cater for all annual environmental conditions.
Charge controller
The MPPT charge controllers can harvest up to 30% more energy in clouded sky conditions compared to PWM charge controllers. The charge controllers have a load output connection that can be programmed to switch the luminaires off when the energy storage voltage drops to critical levels. This allows for the energy storage units to be protected from over discharge. The charge controllers have integrated temperature sensors that can compensate for thermal environmental changes when charging the energy storage units. The charge controllers use a 3-step charging process with all three charge levels programmable depending on the energy storage selected. We offer a 5-year warranty.
