Abstract
An inline DC feeder DC/DC voltage step-up harness for photovoltaic solar facilities includes a housing, a plurality of PV input connectors, an at least one PV output connector. The housing incorporates a DC/DC converter, and has an input and an output. The plurality of PV input connectors are operatively connected to the housing at the input. The PV output connector is operatively connected to the housing at the output.
Claims5
An inline DC feeder DC/DC voltage step-up harness for photovoltaic solar facilities, comprising:
- a housing containing a plurality of DC/DC converters, each having a two-pole input and a two-pole output, wherein the outputs of the DC/DC converters are connected together in parallel in the housing and provided as an exterior two-pole output from the housing;
- wherein each pole of the input of each of the plurality of DC/DC converters is terminated with a connector adapted to connect to a corresponding connector operatively connected to an existing circuit;
- and
- wherein each pole of the exterior output from the housing is terminated with a connector adapted to connect to a respective corresponding connector operatively connected to a DC combiner box.
An inline DC voltage step-up system for retrofitting a photovoltaic (PV) solar facility to provide a new, higher-voltage output, the system comprising:
- (a) an inline DC feeder DC/DC voltage step-up harness, including:
- (i) a housing,
- (ii) a plurality of DC/DC converters disposed within the housing, each DC/DC converter having a two-pole input and a two-pole output,
- (iii) wherein the outputs of the DC/DC converters are connected together in parallel in the housing and provided as an exterior two-pole output from the housing,
- (iv) wherein each pole of the input of each of the plurality of DC/DC converters is terminated with a connector adapted to connect to a respective corresponding connector operatively connected to an existing circuit, and
- (v) wherein each pole of the exterior output from the housing is terminated with a connector;
- and
- (b) a DC combiner box having a two-pole input, terminated with connectors coupled to the connectors of the exterior output of the inline DC feeder DC/DC voltage step-up harness, and an output connected to a load.
A method of retrofitting a photovoltaic (PV) solar facility to replace an existing lower-voltage module, connected to connectors that terminate output circuits from the PV solar facility, with a new higher-voltage module, the existing lower-voltage module providing output voltage to a load at a first voltage, the method comprising:
- (a) providing an inline DC feeder DC/DC voltage step-up harness and a first DC combiner box, wherein the inline DC feeder DC/DC voltage step-up harness includes:
- (i) a housing,
- (ii) a plurality of DC/DC converters disposed within the housing, each DC/DC converter having a two-pole input and a two-pole output,
- (iii) wherein the outputs of the DC/DC converters are connected together in parallel in the housing and provided as an exterior two-pole output from the housing,
- (iv) wherein each pole of the input of each of the plurality of DC/DC converters is terminated with a connector, and
- (v) wherein each pole of the exterior output from the housing is terminated with a connector;
- and
- (b) disconnecting a second DC combiner box from the plurality of connectors that terminate output circuits from the PV solar facility;
- (c) after disconnecting, connecting inline DC feeder DC/DC voltage step-up harness to the output circuits from the PV solar facility by connecting the respective connectors together;
- (d) connecting the first DC combiner box to the output from the housing via the respective connectors;
- and
- (e) thereafter, providing an output voltage to the load at a second voltage, the second voltage being greater than the first voltage.
