Achieve the near impossible with Blue Energy

15 Kw Blue Energy – 3 phase Inverters

The Challenge

A few months ago Orbic Solar was given the opportunity to design and install  a Solar System for a upmarket property in Camps Bay area.

The request was to design a system, to power a large family home, with air conditioners, garden pumps, pool pump, water filtration pumps and various other appliances ( The Complete Home)  , but the biggest load request was the added requirement to power the 3 phase elevator-lift of the home. The lift covers 3 stories and can lift a maximum weight capacity of around 800 Kg.

When the lift starts, the motor and control board can draw a large amount of power and this value is a variable, which basically means it changes every time based on the weight. As the total weight lifts up the power also fluctuates and movement also have an effect on the power needed. Now for a connection that is connected to Eskom its not a problem, because most of the time Eskom is stable, and we don’t care about this need.  So when the lift need to move it will influence the total amperage or power consume. But for an Off-Grid system that is only using Eskom as a backup, it really is not that simple.

So the big question is how do you still use the same capacity size inverter as competitors, but handle the current required on start-up better without destroying the equipment or the need of over sizing the inverter and increasing the prices. The goal of the design was also to not use oversize size inverters to handle the extra power but to find a more efficient and smarter solution that use better power management to achieve the same results without increasing the  budget. This was  a huge challenge by itself, then we still need the system to be stable, flexible, reliable plus the options to expand the system including a remote management solution. The system further have to be extremely efficient and  have lower than normal operating and maintenance cost.

Blue Energy’s Answer

So the answer was to design a solution that uses Blue Energy’s  3 x Victron 5KVA Quattro units for 3 phase operation.

These Blue Energy inverters can bypass current, and combine current form various sources.

Blue Energy also can also deliver much higher loads power for extended time period to handle the startup power loads for the lift and other spikes from the pumps. The extended power spike capability is what makes it possible to achieve nearly the impossible. By using smaller units to handle high power spikes with reliability and no compromise to system guarantees.

We also opted for Lithium batteries that can handle up to 150A of power at 50V at around 12.5Kw/h of storage.
