1. Examples of some of our UPS Systems
Assembly and installation

2. Small-Scale Embedded Generation System
15KVA DC Coupled + 3kVA AC Coupled – Home installation
2.7kWpeak PV panels connected to grid tie inverter. 13.4kWpeak PV panels connected to MPPTs.
Grid tie inverter – AC coupled on output of the Victron system.
Power controlled from Victron system by means of frequency
shifting if grid feed-in is disabled on the Victron Inverter chargers.
4 stage passive cooling system in the battery room.
15KVA DC coupled bi-directional Inverters with
MPPTs and a 4-stage passive cooling for inverter
cabinet. Manual system bypass possible.
Automatic source selection and a
second stage of ant-islanding.
Manual isolation also possible.

15KVA DC Coupled + 3kVA AC Coupled – Home installation
Tubular Plate, Flooded Lead Acid batteries with automatic electrolyte top-up, electrolyte stirring, gas extraction and temperature compensation.
Container equipped with 2 * 48kWH battery banks with battery conditioning system, 3kVA grid tie inverter, 14kW DC generator and a socket for 15kVA AC
generator and a 4-stage passive cooling system.

15KVA DC Coupled + 3kVA AC Coupled – Home installation
The generator is PLC managed and reduces speed as the load reduces, always running at maximum torque for any given output ensuring maximum
fuel efficiency and minimum carboning. This engine is equipped for 1500hr service intervals compared to the 250hr intervals of standard engines.
A 14kW DC Generator programmed for a 4-stage tubular flooded battery charge regime, is the secondary source of back-up. The power system is also
equipped to take as third source of back-up, an AC generator of 15kVA, which can be plugged in should it ever be required, which is highly unlikely.
