Project Details

HmT Electrical’s end-to-end planning approach was to design a complete solar solution system using the ultimate equipment. This approach derived from value-added engineering and cost reduction – which benefits the client enormously.

Every aspect of this project starting from design, installation all the way through to maintenance was constructed to ensure the highest return on investment (ROI) for our client.

The two Victron Inverters in this system were designed to run in parallel with each other. This was done to ensure no overload conditions occurred, as well as to keep up with the client’s power needs.
With this system in place, we can monitor Victron Energy Remote Management (VRM) Systems and advise clients pro-actively of incurring technical issues, whilst working on their settings remotely.

The system comprises of the following:

2 x Victron MultiPlus-II 48/5000/70-50
1 x Victron MPPT 250/100
1 x Victron Cerbo GX
1 x Carlo Gavazzi, single-phase energy meter
5 x BYD Battery Box Premium LVS 4.0kWh
1 x BYD Battery-Box Premium LVS PDU
1 x BYD Battery-Box Premium LV BMU (IP55)
Solar Panels were outsourced by the client (16 x Canadian 360Wp)

Cerbo GX
This communication center allows perfect control over your system and enhances performance.

Multiplus-ll 5 kVA
This multifunctional inverter/charger, with an external current sensor option, extends the PowerControl and PowerAssist function. The MultiPlus-ll compensates for insufficient grid power with energy from the battery. When the load reduces, the spare power is used to recharge the battery.
Up to 6 Multis can operate in parallel to achieve higher power output. In addition to parallel connection, three units of the same model are configured for 3-phase output.

BYD Battery-Box Premium LVS
The BYD Battery-Box Premium LVS is a lithium iron phosphate (LFP) battery pack with an external inverter. Patented Internal Plug Design Requires No Additional Wiring. Cobalt Free Lithium Iron Phosphate (LFP) Battery: Maximum Safety, Life Cycle, and Power. Scalable from 4 kWh to 256 kWh.
