Advantages of On Grid Solar System

1. Lower up-front cost: On-grid solar systems do not require energy storage, such as batteries, which can be quite expensive. This results in a lower upfront cost.

2. Easy maintenance: The main electrical grid provides backup power during periods of low solar output, such as cloudy days or night-time. This eliminates the need for the homeowner to maintain a separate energy storage system.

3. Increased energy independence: By generating their own electricity from solar panels, homeowners can reduce their dependence on the main electrical grid and take control of their energy usage.

4. Financial savings: On-grid solar systems can significantly reduce homeowners' energy bills, as they generate their own electricity from a clean, renewable source.

5. Government incentives: Both, Central and State Governments provide subsidies and also various incentives, such as tax credits, to encourage homeowners to adopt renewable energy sources like solar power.

1.The power of UPS generally refers to the output power. The input power is bigger than the rated power, especially when the battery has discharged after a period of power stopping. The input rectifier not only supplies power to the load, but also charges the battery. The maximum current can reach 1.3 times of the rated current. If the battery pack capacity is particularly large, and the host is equipped with a charging module, the current will be greater.

2.UPS itself is a kind of non-linear load, which will produce some harmonic current feedback to the input grid, and will increase the temperature of the generator ball. If the generator load ratio is too high, it may burn the ball.

3.The load behind UPS to the generator is all selected by the internal circuit of on grid UPS to be battery or city power/power generation. It is one-time loading. There is no soft start or other way. If UPS is loaded at 80% load and the impulse current is calculated at three times, all of them exceed the rated output of the generator configured at two times. The frequency and voltage of the generator will decrease at this time. UPS detects this change and will immediately switch to the battery for power supply.

Therefore, the capacity of the generator with UPS should be large enough, not as simple as 2 times the capacity. It should be configured according to the specific situation.
