During 2018, Sunray Power Company installed our first SuperCap high energy solar storage device in Zambia. This is a first in the country and introduces Zambia to a new era in energy storage.
The supercap, with a 45 year service life and 100 000 cycles, is the ideal companion for PV solar. The very high charge and discharge rates, coupled with incredible cycle life is the perfect match for the intermittent nature of PV solar.
The system comprised of
- 6x 3.55kWh Sirius SuperCaps
- 2x 5kW Mecer 5kVA Inverters
- 24x 320W PV Panels
- Aluminium roof mount structure
- Comprehensive battery monitoring
This installation was done on 3 May on a farm near Mukushi. The system comprised of a large, 2 x 3 x 200Ah battery bank, connected to our very popular 3kVA eMax inverter and powered by 9 x 250W Solar panels. In addition to the built-in MPPT of the inverter, an additional charger was used for the extra panel capacity. This turned out to be a very elegant system for the clients’ need.
Chongwe AC Pump Conversion
On 20 April, Sunray did an installation in Chongwe that converted an existing pump that was powered by a generator to run from solar power. This conversion used one of our highly sophisticated solar pump controllers, and, together with high quality panels and technical expertise, will now pump water for free deep into the future.

AAR Japan Offgrid with BMS
This is an offgrid system with our battery monitoring system. 4x 250W solar panels provide power to the system while the BMS keeps any eye on the usage and battery state.
PV Training Feedback
Sunray presented 2 PV training courses: A 2 day basic training, followed by a 3 day installation training. The installation training focused on the design and building of a Hybrid PV solar system, as well as the design, sizing and testing of solar water pumping systems.
