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.

Technical:

5kVA MultiPlus Inverter

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.

Technical:

1Hp, 220V single phase AC Pump

9x 120W High Voltage solar panels

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.

Esther School: Tilted Panels

On 8 May, Sunray installed an off-grid solar system at Esther School in Chongwe.

This system included a tilted panel frame, based on our engineering grade aluminium panel mount structure. The system is used to provide power for a section of their classrooms.
