Inverter will automatically wake up with the restoration of grid power or solar power.
Solar installation professional's can help you to determine the type and size of the system most suited for your needs.
The solar energy available is less than the energy consumption.
To avail maximum economic benefit it is always better to use solar power directly (day time ) for the load instead of storing energy in the battery and then using that for the load.
Yes, only if the inverter, battery and other control systems are capable of handling it.
Yes, In the remote villages where the grid power is at a distance, UPS can be used as a standalone power system.
In case of no solar power, battery will continue to supply load till it remains with charge of about 50 %. Then load will switched to grid power. This is because the solar energy would have charged the battery full and that needs to be utilized on priority also. Also by discharging the battery to about 50%, It is ready to charge when the solar energy comes back.
Cooling fans starts running when the internal temperature reaches 65-70 deg. c and turn off when the internal temperature returns to 55-60 deg. c
Inverter is protected from Lightening, Over load, O/P short circuit, O/P Phase reversal, Battery over voltage, Battery under voltage, High and low voltage, Battery reversal etc.
It is not required or advised. Keep the inverter charging. If you leave the battery uncharged for the long time it may drain off fully and battery life will suffer.
A MPPT (Maximum power point tracking) charger is the charge controller with power electronic control device designed to control by microprocessor embedded with MPPT algorithm firmware to maximise the amount of current going into the battery from PV panels. A MPPT charge controller works as DC – DC converter by using knowhow of PV panel and battery characteristics to get the highest conversion power output from PV panels and safety charge the battery.
If there is load connected, solar power will go to load. In case of no load/ less load, the entire/ balance solar power will go to the battery. First priority is load and then the battery.
How often you use and recharge the batteries will determine the frequency of watering . Also, using batteries in a hot climate will require more frequent watering. It is best to check your battery water level frequently and add distilled water when needed, Never add tap water to your battery. Batteries are provided with fluid level indicators which help in determining when and how much water needs to be added.
This depends on the storage battery capacity and the PV module rating. It can be extended to any number of hours, by adding more numbers of PV modules of battery etc.
Under normal conditions the rechargeable batteries should last for several years. Afterwards you have to buy new ones from the supplier or dealer near to you.
Solar systems last for about 20-30 years. Other electrical components such as inverters and batteries vary as per specifications. But it doesn't mean that after 25 years, your solar panels will stop producing electricity. They will still produce electricity but less than their ratings.
In most parts of India, a 1 kW system can generate 1250-1500 units (kWh) per year. So for a household usage of average 300 units per month (annual consumption of 3600 kWh), a 1 kW system can take care of roughly 1/3rd of annual energy requirement. Whereas, a 3 kW system can help you go off the grid!
Normal Solar Pumps are designed to lift water from Wells up to 200 feet depth and delivery of the pump is varies from 15,000 L per day to 75,000 L per day. Special designs are available on request.
