Abstract

Renewable electrical energy is provided with aspects and circuitry that can harvest maximum power from an alternative electrical energy source (1) such as a string of solar panels (11) for a power grid (10). Aspects include: i) controlling electrical power creation from photovoltaic DC-AC inverter (5), ii) operating photovoltaic DC-AC inverter (5) at maximal efficiency even when MPP would not be, iii) protecting DC-AC inverter (5) so input can vary over a range of insolation and temperature, and iv) providing dynamically reactive capability to react and assure operation, to permit differing components, to achieve code compliant dynamically reactive photovoltaic power control circuitry (41). With previously explained converters, inverter control circuitry (38) or photovoltaic power converter functionality control circuitry (8) configured as inverter sweet spot converter control circuitry (46) can achieve extraordinary efficiencies with substantially power isomorphic photovoltaic capability at 99.2% efficiency or even only wire transmission losses.

Dependent claims

A coordinated photovoltaic electrical energy power system comprising:

at least one photovoltaic DC-DC power converter responsive to an overcurrent condition and having a photovoltaic DC converter output;
a coordinated converter functionality control circuit configured and arranged to reactively alter converter switching in a manner that does not negate an ability to convert but retains the ability to yet again convert and does not prevent resumption of converter switching to again convert when appropriate, and to achieve photovoltaic disable mode converter functionality control of said at least one photovoltaic DC-DC power converter that deactivates said photovoltaic DC-DC power converter from converting DC photovoltaic input to DC photovoltaic output upon said overcurrent condition;
a load responsive to said photovoltaic DC converter output;
and
a photovoltaic power output of said photovoltaic load,
wherein said coordinated converter functionality control circuit that reactively alters converter switching to achieve photovoltaic disable mode converter functionality control of said at least one photovoltaic DC-DC power converter comprises a coordinated converter functionality control circuit that reactively alters converter switching to achieve dynamically reactive mode of conversion switching control so that as one condition changes, nearly instantly a desired different conversion control mode can be appropriately caused, and wherein said dynamically reactive converter switching control is a dynamically reactive building code compliant converter mode of conversion switching control of said at least one photovoltaic DC-DC power converter that switches a mode of conversion for building code compliance.
