FACTORY LOAD ON EB
FACTORY LOAD ON SG
Features Of Overleap Solar Generator
- Normally, the load is run directly by utility power. As shown in the schematic diagram A.
- When utility power is not available a Diesel Generator can drive the load independently.
- The solar Generator drives the load directly just like a DG. It does not need any support from EB for driving the load. The role of utility power is only topping up the left-over charging requirement of the batteries after the solar option is exhausted. Hence the required capacity of EB is equivalent to the charger capacity. This way the contract demand on EB gets reduced to the capacity of the charger. See the schematic diagram B.
- A Solar generator has three main components. Solar panels which utilizes available solar power, the storage batteries from which energy is delivered to the load and the integrator unit which manages the load in coordination with the power storage, power generation and power requirement.
- The entire load connected to the SG will draw power from its energy tank-battery bank
- The solar generator tops up its energy tank from solar panels. However, flexibility to receive charge from other sources of electricity to top up the tank is inbuilt in it.
- The solar generator has a life equivalent to 25 years of useful solar panel life.
- The electricity delivered is of steady voltage, rated frequency, unit power factor and lower harmonic distortions giving following benefits
- The power generated from the solar generator is the cheapest power, the cost of energy being Rs 2.5 to Rs 2.8 / unit during its life span of 25 years.
Energy tank of Solar Generator
- Energy tank of a solar generator is its battery bank
- The battery bank is made of 2V single cell Lead Acid Flooded Battery with proprietary chemical composition capable of delivering high surge currents .
- Time tested rugged design specially made for catering to rough loads from industries and commercial concerns.
- Battery arrays in two tiers formed with fusible link interconnection between individual batteries .
- Series and parallel connection of battery arrays form the battery bank in which performance of any single battery battery has no criticality.
- Battery bank functions under the supervision of a Battery Management System installed in the integrator.
- Fusible link between terminal connections of two batteries in an array isolates any battery in case of its overheating.
- Regulated gasing voltage to control generation of fumes.
- Specially designed Ceramic Vent Plugs to arrest emission of fumes and hydration of batteries.
- Battery Terminals are covered with insulations cap to prevent accidental external shorting.
- Manual isolates and fuse protection for the battery bank.

Overleap SG- The Gen Next Renewable Energy Evolution
- Any electrical load requires a power source for its operation.
- If a power source of adequate capacity is given, any load can be operated. For ordinary AC motors the power source may be EB grid or DG set. But they can also be operated with a Battery bank with an inverter, as is done at home, but with high capacity.
- But only a charged battery bank can deliver power. Hence the batteries are to be charged for operating the load. Solar PV cells in solar panels can be used to charge the batteries with the help of charge controllers
- In short, if adequate number of solar panels are installed, the battery bank can be fully charged and a charged battery bank can deliver power to drive the load with out EB power.
- In case the panels are not adequate in number, there will be shortage of charge in the battery bank. This shortage can be compensated by charging the batteries from EB line using a battery charger like home inverter- battery sets.
- When the solar panel shortage is known in advance, the compensating charger capacity can be designed in advance and installed. This charger capacity will become the load of the system as only this charger is connected to EB line.
- We operate loads using battery bank of very high capacity this way. The power we require from EB for driving the load is limited to the charger capacity only , the rest is managed with solar panels. SG this way is a capacity multiplier.

Comparison With Any On Grid Solar Solutions
| Power for the entire electrical load of the unit is supplied by SG from its battery bank. | No control over power supply. Power is supplied by the utility from the grid as it is. |
| Provides uninterrupted power supply, the unstated factor of production, to the industrial unit. | No control over power supply. Power disruption possible. Industrial unit gets the same grid power as supplied. |
| Incomparable power quality +/- 1 % voltage range and +/-0.1% frequency range. | No control over quality and timing of power supply. Power characteristics unsteady and polluted with Harmonics as supplied by Utility. |
| Responsible for productive power supply to the client. | No responsibility for supply of power. |
| Every watt of solar power is captured, stored and delivered for consumption from the battery bank with minimum conversion loss. | Export to grid is limited by inverter ability to match unsteady solar power input to Grid conditions. Time loss due to mismatches results unresolved. |
| Reactive power from inductive loads effectively utilized getting 15% net fall in power consumption. | No ability to influence reactive power and harmonics generation and reduce power consumption. |
| Dependency on grid supply is reduced by reducing both Maximum demand and energy charges. Bill reduction up to 70 % possible. | Can contribute sparingly to reducing energy charges. No control over fixed charges Limiting ability to reduce Total Electricity Bill. |
