What is an Solar Inverter ?
A solar inverter or photovoltaic (PV) inverter, is a type of electrical converter which converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
Why do we need Solar Inverter ?
1. Convert DC to AC power
The basic function of an inverter is to convert the direct current (DC) power that solar panels create to alternating current (AC) power that is usable in homes and businesses or fed directly into the grid in front-of-the-meter projects (utility-scale solar arrays).
2. Maximize power output
Inverters are responsible for continuously tracking the solar array’s voltage to identify the maximum power at which the modules can operate, according to PVEL. If shading occurs from environmental factors or if modules are degraded, the inverter can accidentally identify the wrong peak in the string, thus reducing the overall energy production of the system.
3. Interface with the grid
Smart inverters, the new frontier of solar inverters, have advanced from one-way communication to two-way communication with the grid, assisting with grid-support functions. Thanks to advanced software, smart inverters can perform specific grid-supportive functionalities related to voltage, frequency, communications and controls.
One of the most important grid assistance capabilities of smart inverters is the ability to ride through small disturbances (for example, voltage changes). Smart inverters can switch into standby mode in the case of a voltage change and observe how long the disturbance takes place, then turn off only if the disturbance lasts too long. This ensures that there are minimal voltage fluctuations on the grid due to distributed resources turning all the way off and halting power production.
4. Report on power production
Inverters make it possible for solar owners to keep track of the power output of their solar systems. Most inverters have communications capabilities via hardwired ethernet, Bluetooth or Wi-Fi, according to PVEL. This communication connectivity can put inverters at risk for cyberattacks, but scientists are working on solutions to mitigate this possibility..
Solar owners can view error codes, diagnostics and power production information from inverters on their computers or even on dedicated smartphone apps like the one offered by SolarEdge. Large-scale solar owners may want to additionally invest in advanced monitoring services to help diagnose and fix issues on multi-inverter arrays.
5. Ensure safe system operation
Inverters are required to shut down in the event of an electrical arc, which can be caused by system aging and material degradation, according to PVEL. They’re programmed to identify these arcs, but PVEL found not all inverters do so effectively.
Rudra Enterprises using vast experience of designing offers state-of-art Hybrid Solar Inverter-cum charger system. It consists of MPPT Solar Charge Controller with Hybrid Inverter. The same inverter can charge the batteries from Solar or Mains supply (wherever available). The Inverter can thus both charge the batteries or supply the AC power to the connected Loads.
This hybrid Inverter senses the availability of solar power, utility power and gives charging preference to the solar power charge and only switches to the utility mains supply when the solar power is not available. The design is to give to the consumer maximum benefit from the sun and minimize the electricity bill.
A purely solar power solution for general lighting load is very expensive as far as initial investment is concerned. Also, due to frequent power failure, a regular backup UPS/Inverter barely gets time to charge the battery from mains. This Hybrid version combines solar energy and mains utility to give an excellent solution by providing the best of both worlds. This Hybrid Solar Inverter from Rudra Enterprises is available from 800 VA to 50KVA in wide input voltage range.
