Solar UPS Inverter

A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic 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 ant islanding protection.

CLASSIFICATIONS:-

Given below are some specifications of a solar UPS shown above. Please note that the specifications will change with a different model.

Charging process.
5 stage charging process
Data logged
Battery usage
Number of time battery discharged till warning and number of times battery charged
Last Fault record.
Useful for post fault analysis
Protections
Unique protection schemes have been Incorporated to enhance readability
Reverse phase
In the event of phase voltage wrongly connected to the inverter output safe shut down will occur
Overload
In the event of overload system will shut down and restart 5 times
Short circuit (Batt Mode)
A short circuit on the output will be detected separately and lead to lock down.
Over temperature
Excessive temperature rise due to poor cooling or fan failure will cause shut down
Under charged battery
The system detects the number of charge and discharge cycles. In case the battery not getting adequate charge and is repeatedly being discharged affecting its life the system will lock down
Battery loose
Sparking or spikes on the dc bus will cause safe shut down and lock down.
Battery deep discharge
Soft current builds up in case of deep discharge battery
Battery bad
In event a cell is dead or shorted a time out circuit will prevent prolonged charging.
In order to provide enhanced flexibility for the wide range of applications many features in the card are for the wide definable at your end.
