Different solar projects

Key data: 100 kWh / 40 kW / 33 kWp - in Lagoa - Algarve

Solar

Large, three-phase system – almost industrial in scale.

72 designer solar panels with black frames, each 455 Wp, mounted on a south-facing aluminum frame
with shade-free spacing and ground anchors.

Total output nearly 33,000 kWp – inverters approximately 90 m away. Voltage drop-free operation with
a high voltage of 600-750 VDC via series connection.

Hybrid Inverter

2 large, three-phase, 20.000 kW hybrid inverters operating in parallel with emergency power supply.
Connected to a 30 A/20.7 kVA three-phase EDP line, only for longer dark periods.
40.000 kW total output, with each phase capable of delivering a maximum of 20.000 kW.

Lithium Batteries

100,000 kWh of battery power with six 17,500 kWh LiFePO4 batteries in two towers, each with over 50 kWh capacity,
connected in parallel via 2 cm thick copper busbars. The batteries are stacked three high and rest on a sturdy battery cart,
allowing for easy maintenance of the entire system by simply sliding the approximately 600 kg battery block out of the way.
The batteries are our own design and consist of the latest generation of lithium iron phosphate cells,
hand-selected from the best production lines.

Up to 10,000 kW can be drawn simultaneously from each battery, corresponding to a potential total output of 60,000 kW.
Since both inverters together can draw a maximum of 40,000 kW, the maximum total load is less than 0.4C.
The manufacturer recommends a maximum of 0.5C (50% of capacity) and guarantees 6,000–8,000 full cycles
if this value is not exceeded.

This corresponds to approximately 25 years.
