Methods and systems for connecting a photovoltaic module and an inverter having an input capacitor are presented. The photovoltaic system includes a maximum power point tracking (MPPT) controller coupled between the inverter and the photovoltaic module. The MPPT controller includes a direct current (DC) converter configured to reduce, in a forward buck mode, a voltage of the photovoltaic module, to supply power from the photovoltaic module to the input capacitor of the inverter. The photovoltaic system also includes a microcontroller unit (MCU) configured to control the DC converter to allow the photovoltaic module to operate at a maximum power point, and to increase, in a reverse boost mode, a voltage of the input capacitor of the inverter, to dissipate power from the input capacitor in the photovoltaic module, and the MPPT controller is configured to, based upon one or more triggers.

Systems and methods for quick dissipation of stored energy from input capacitors of power inverters

Systems and methods for efficiently allowing current to bypass a group of solar cells having one or more malfunctioning or shaded solar cells without overwhelming a bypass diode. This can be done using a switch (e.g., a MOSFET) connected in parallel with the bypass diode. By turning the switch on and off, a majority of the bypass current can be routed through the switch, which is configured to handle larger currents than the bypass diode is designed for, leaving only a minority of the current to pass through the bypass diode.

Solar panel junction boxes having integrated function modules

A cascading regulation system connected to a number of serially connected power sources and uses multiple regulators having different cutoff voltages to provide an output for the local power consumption unit. Each of the regulators is connected to a subset of serially connected power sources and so configured that if the voltage generated at the lowest tap is no longer sufficient for a stable supply to the local power consumption unit, the next higher regulator takes over, and the output voltage drops in small steps reflective of that takeover of the next higher tap. When the voltage generated across a subsection grows, a lower connected tap may take over again, producing a slightly higher output voltage for the local power consumption unit. The cutover steps are chosen such that the output voltage range matches the range given as the acceptable input range for the local power consumption unit.

System and method for low-cost, high-efficiency solar panel power feed

Systems and methods are herein disclosed for efficiently allowing current to bypass a group of solar cells having one or more malfunctioning or shaded solar cells without overwhelming a bypass diode. This can be done using a switch (e.g., a MOSFET) connected in parallel with the bypass diode. By turning the switch on and off, a majority of the bypass current can be routed through the switch, which is configured to handle larger currents than the bypass diode is designed for, leaving only a minority of the current to pass through the bypass diode.

A system and method to collect energy from generation systems such as, for example, wind farms or solar farms with widely distributed energy-generation equipment. In some cases, static inverters are used to feed the energy directly into the power grid. In some other cases, back-to-back static inverters are used create a high-voltage DC transmission line to collect power from multiple generation sites into one feed-in site.
