Engaging with a client who not only has a wealth of electrical expertise but also a clear vision for their energy needs was both an honor and a challenge. As a retired electrician, our client knew exactly what they wanted—a state-of-the-art system that could deliver unwavering reliability and efficiency. Their 5-star review stands as a resounding endorsement of our commitment to excellence. We didn't just meet their high expectations; we crafted a bespoke solution that encapsulates the perfect synergy of professional acumen and client insight. This project is a glowing testament to when experience meets precision, resulting in an energy solution par excellence

For our latest endeavor, we partnered with a client who already demonstrated commendable energy management practices. The goal was not just to address the inconvenience of load shedding but to elevate their energy independence to new heights. Armed with a substantial battery capacity and an expansive solar array, we meticulously designed a system that promises not only to drastically reduce their reliance on grid power but also to harness solar energy with remarkable efficiency. This setup, a blend of foresight and advanced technology, is set to redefine what it means to be self-sufficient in energy usage.

Essentially uses geyser as a dump load once battery is full. Also, run this 'signal' via Relay1 on CerboGX and using NodeRED to disconnect during overload;

Embarking on a new journey with our latest client, the mission was crystal clear: to conquer the persistent challenge of load shedding and to significantly slash their grid power dependency. By leveraging the advanced capabilities of Victron technology, we've designed a system poised to revolutionize their energy landscape, setting the stage for substantial efficiency gains and a greener footprint.

Upon receiving a commendable referral from a satisfied neighbor, our client entrusted us with a significant challenge: to conquer load shedding woes and usher in substantial energy savings. Opting for quality over cost, they chose our premium services despite our quote being the highest. Embracing this trust, we embarked on a meticulously phased project, utilizing the extraordinary flexibility of Victron's range. The result? A testament to efficiency: a mere 1 kWh drawn from the grid over a remarkable 90-day period (Jan'23 - Apr'23).

Components:

• Victron MultiPlusII 48/5000/70 Inverter Charger
• Victron SmartSolar 150/60 Charge Controller
• Victron CerboGX + Touch50;
• Victron Lynx Distributor
• 2x BYD Flex Lithium Batteries
• 6x 540W Axitech Premium PV Modules

Notes:

• ESS activated on 30% DoD

Customer approached us to help resolve loadshedding in a business that lost about 4-6 hours of production per day during normal business hours, resulting in severe loss of revenue and severe overtime in order to keep commitments. They have a few commercial printers, power stations for the graphics teams and a few other smaller electrical appliances they use for day-to-day processes.

Components:

• Victron MultiPlusII 48/5000/70 Inverter/Charger;
• Solar MD 14.3kWh Lithium Batttery
• Victron CerboGX + Touch50
• Victron Lynx PowerIn DC Busbar

Notes:

• System runs in ESS enables on "Keep Batteries Charged"

This project was completed over 7 phases, once again showing the incredible modularity of the Victron product range. The customer started with a 5kVA Inverter and 5kWh battery backup system, which expanded to a 10kVA inverter and 20kWh battery backup with 26 panels (11kWp) of PV power. We also have a EV charger installed, and due to have a 3ph grid supply, we installed it so that he has the option to either fast-charge (up to 22kW) on 3 phase power, or a regular charge (8kW) on single phase power. The Victron EV charger also has the option to use ESS and only charge with access PV power once batteries are full and loads are supplied.

• 2x MultiPlusII 48/5000/70
• 2x FreedomWon 10/8
• 1x Fronius 8.2kW with 11x 415W JA on East (MPPT2) and 11x405W Canadian Solar on West (MPPT1)
• 1x SmartSolar MPPT 150/35 with 4x 530W JA Solar (East)
• Cerbo GX with GX Touch
• Lynx Power In
• ET340

Assistants:

• ESS activated - currenlty DoD on 20%
• Programmable relay - We are using the aux contactor (continuity relay with 230V from Grid) on MPII (Master unit) to open and close on high (99%) and low (70%) of battery SoC. The signal is used on AC contactors with delay timers to move additional loads from L2 and L3 to L1 (on Grid Side of inverter). This allows us to use additional PV on heavy loads of the underfloor heating.

Customer familiar with the quality of Victron approached us for an installation on a holiday home in Britannia Bay. This house was to become the new primary residence over time. We proposed a phased approach (there was construction to come) in order to facilitate all current needs and available roof space, and then to add more PV and battery later as construction conclude and needs require it.

One big requirement was to charge the Volvo XC40 Recharge with solar power.

Components:

• 2x Victron MultiPlus-II 48/5000/70 Inverter/Chargers
• Victron RS 450/100 MPPT with 3.5kWp PV (for now)
• Victron EV Charger
• Victron CerboGX+Touch50
• Solar MD 14.3kWh Lithium Battery

Notes:

• ESS Enabled;
• Generator-Start-Stop enabled on AC-Out2 to enable loads up to 40% of battery during power outages;
• EV charger is still in manual, waiting for updated firmware to make it part of ESS;

A retired couple approached us to:

• Eliminate load shedding and 
• save some on electric bill;

With an 5kVA inverter, 5kWh lithium ion battery and a few panels we accomplished just that.

As further benefit, we installed a small LED light to give them an indication when it is load shedding (the system had to be installed in a building separate from the main house)

Components:

• Victron MultiPlus-II 48/5000/70-32 Inverter;
• Victron SmartSolar 150/45 MPPT;
• Victron CerboGX + Touch50;

• 6x 410W Canadian Solar PV modules;

Notes:

• ESS enabled with BatteryLife;
• 12V Aux Relay on the MP-II used to power a small LED light to indicate load shedding ;

The first request was to "power a lift so grandkids do not get stuck", we advised them to get a 5kW so we can power lift, lights and all the plugs.

On the second phase we added PV panels, but we added so many the battery was full before 9am!! Over the 3rd and 4th phase we expanded the battery bank to 20kWh.

Components:

• Victron MultiPlus-II 48/5000/70 Inverter;
• Victron SmartSolar 250/100 MPPT;
• Victron Cerbo GX + Touch50;
• 4x Freedom Won Lite 5/4 Lithium Batteries
• 12x JA Solar 535W PV modules

Notes:

• ESS enabled
• Generator input on manual changeover

Customer required to eliminate load shedding and reduce grid consumption. Phase one was a 3kVA inverter, 3.5kWh backup and a 15kWh/day PV Generator. We achieved 50% grid consumption In phase 2 we expanded the backup with another 3.5kWh, reducing the grid consumption with an additional 10-15% an doubling the backup duration during load-shedding.
