Introducing the parallel HV solar connection and its advantages in hybrid dc and ac microgrids.
The converter is a low-cost and low component add on to the solar panel. It has a small form factor which permits it to replace the junction box on a PV panel, reducing costs. This can be done by the panel manufacturer. This converter operates on patentable technology built on fuzzy logic, which enables it to form a microgrid with other converters or groups of neighbouring converters. Interesting grid topologies are possible both DC and AC and combinations of both, (hybrids). Connection to mains grid as grid extensions or enhancements are enabled by the smart inverter.
The HVPLC uses powerline communication to relay information to and from the converters to the inverter and energy management system. This enables rapid shutdown capability, temperature, and voltage monitoring and control.
- Technology agnostic and easy to design and install while maximising wire current carrying capacity.
- Multi facing roof installations.
- Reduces effect of cloudy conditions, panel soiling, shading, and aging
- One panel and converter enough to exploit solar both ac and dc. The idea is to start small. As more space or financial resources become available, more panels can be installed and connected to the microgrid inverter and / or the dc microgrid.
- Delivering output of 360V to 420V, enough to power an inverter as a single panel of up to 400 Watts.
- Capable of forming a dc microgrid with or without our microgrid optimised battery inverter.
- They have galvanic isolation, for safety.
- Anti-Arcing technology.
- Upgradable firmware
No effort has been spared to ensure the acceptability of the technology in this renewable energy revolution. DC arcing, a major issue especially in roof applications, has taken a lot of effort to bring the chances of this happening to zero. The efforts include software and mechanical methods to prevent or extinguish the arc when it ever happens.
