First SuperCap

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

Zietsman 3kVA

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.

Hybrid Victron System

Sunray installed and commissioned a Victron grid-connected Hybrid system.

Blue Solar 70A MPPT

Color Control with online monitoring

4x 200Ah Batteries

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.
