Partner with an innovative, trusted and experienced service provider.
Nestled inside Route 21 Corporate Park lies the Vigamode Terrace building. This modern office building hosts 8 corporate tenants inside the 3-story high building. The building owners were absolutely “fed up” with the Municipality, with much of their frustration stemming from the inexplicable and exorbitant service charges observed each month. An Off-Grid solution was clearly the only option.
On the 20th of July 2020, the building celebrated its independence from the Municipality as GreenHouse commissioned the custom Off-Grid system. The building now runs completely Off-Grid, with a backup generator integrated to start and stop automatically when the battery runs low.

Project Remote Net
Introducing RemoteNet, a dynamic company that specialises in the development and implementation of integrated skills development, vocational education and training, and levy and funds management solutions. Their headquarters was in dire need of a power-security solution, as their servers provide critical services to a number of large corporations.
We kicked off our relationship with RemoteNet by initiating discussions to understand their requirement. Anton and his team were routinely having to rush back to the office and connect their portable generator, each time they had a power failure. Keeping their servers powered and online is vital.
While a battery backup solution would have suited that requirement, there is no “rolling” capability afforded by such a system. A hybrid power system was then designed, which incorporated a significant array of solar panels on the rooftop of the building.
The hybrid power system now generates most of the energy required by the building and harnesses the capability to continue operating even in prolonged outages of a number of days, even weeks!
Anton and his team are no longer burdened by the requirement to rush back to the office and start the generator. Now their building runs uninterrupted and is no longer dependent on Eskom.
RemoteNet’s investment in clean energy allows them to join the ranks of home’s and businesses pioneering a sustainable future. Their system will offset an estimated 17 tons of carbon dioxide every year.

Org's Home Power Station
Introducing Org’s beautiful home in one of Pretoria’s finest country estates. A generator solution would certainly be frowned upon in this tranquil country estate, where a clean energy hybrid power system would be far more appropriate.
Increasing grid power failures as well as the ever-increasing electricity tariffs justified a premium and effective system for this elegant and modern home.
GreenHouse designed a state-of-the-art 3-Phase hybrid power system using industry-leader Victron Energy equipment and paired to a lithium battery bank from Pylontech.
The entire system is monitored, sending alerts to Org and his family when necessary (e.g. Grid power failure). The monitoring system allows them to see important details, including:
- Solar Energy Generated
- Home Energy Consumption
- Grid Energy Consumption
- Battery State-of-Charge (SOC)
All of this monitoring data is stored in the cloud and can be accessed through the Victron App, called VRM.

The Doran Home
Meet the Doran family and their beautiful home in Irene, Pretoria.
The Doran’s embarked on a journey to install a solar power system and were steadfast in doing their homework and understanding the various different architectures and equipment manufacturers. GreenHouse, alongside a number of other competitors, were invited to propose and quote on an appropriate system for their needs.
Sizing the system appropriately requires quality information about the home’s consumption profile and daily energy requirement. While monthly utility bills provide some of this information, they do not provide the entire picture and this calls for the temporary installation of a high-resolution power monitoring device.
Once the power monitoring data was extracted from the device, the GreenHouse team got straight to work in designing the optimal system for the Doran home.
The Doran’s now enjoy power security (backup power) as well as a significantly reduced electricity bill through solar power generation. Continuity of lifestyle is now ensured and their investment is hard at work, saving them money each day.
