Need of Solar Combiner Boxes
In large commercial solar photovoltaic (PV) arrays, multiple solar modules are connected in a string to build the voltage as required by the inverter. Multiple strings of solar modules are then combined in parallel to form the array. A solar combiner box can be thought of as a gate keeper for your solar power solution.
Solar Combiner boxes are used to combine the inputs from multiple strings of solar panels into one output circuit for connection to the inverter. Sometimes this is also called as Photovoltaic (PV) Combiner Box. On a single-line diagram, the solar photovoltaic combiner boxes look like a "reverse-fed distribution board". Instead of breaking one feeder into multiple branch circuits, the combiner “combines” multiple branch feeds from solar strings and groups them into one output. This output in turn serves as an input for the inverter. Sunipod’s combiner boxes support from one PV panel to many in series, and ranging from a single low voltage panel to multi-panel high voltage arrays for all systems.
Design of Solar Combiner Boxes
Solar switch gears form an added protection and thus are one of the most important components in a solar PV system. A solar photovoltaic combiner box commonly has input over-current protection devices for strings, and their combined bus into a single main output. As part of the system design Sunipod provides its combiner boxes housing site specific components, such as a DC disconnect, surge protective devices and, in some cases, string monitoring hardware. They also protect downstream solar components from any fault during the operation of the solar power solution, such as over-current or over-voltage from solar module string and solar module arrays, temperature rises of solar modules or solar cables used, lightening protection, switching faults, etc.
When comparing two solar combiner boxes with the same internal components smaller may not always be better for long string combiner life. Larger enclosures make field wiring easier by allowing more room to work during installation and maintenance while assisting in better cooling of internal components.
A solar combiner box also reduces wiring & installation costs, making the plant look cleaner and less prone to accidents. This helps in improving the plant uptime as opposed to as exposed wiring subjected to outdoor weather and attack from birds and animals.
Solar photovoltaic combiner boxes are also help in monitoring the health of the plant periodically. They offer higher granularity in error analysis, reducing the time required for isolating problems which can be a very time consuming activity. You can directly locate faults to a particular string, but this can be possible only if you have solar combiner boxes and a monitoring technician.
A proper long-term maintenance plan can help monitoring the electrical connections to insure a high reliability and long lasting field installation. Solar combiner Boxes continue to carry current even when disconnected, please take help of qualified personnel before you start installing or trouble shooting your combiner boxes.
