Energy Storage Battery
As an alternative to solar power, MELASTA is also introducing a battery-only tariff The battery pack is charged overnight at low-cost night-rates, and the power is used during the following day’s peak periods, saving you a small fortune. MELASTA UPS Series battery is suitable for all critical power UPS. Designed with high-density thin prismatic technology, the UPS battery will deliver up to 50% additional watts per cell than the typical UPS battery of equal footprint.

Energy Storage Battery Packs

Melasta Provides energy storage solution for wide range of applications. It has standard products which could be used for replacement for energy storage. It’s high quality product replaces the lead-acid batteries efficiently. These batteries are with plug and play replacement. These batteries have built-in BMS System which controls the battery for charging and discharging. BMS have multiple options for communication protocol such as Bluetooth, Wifi and RS485. 

Melasta Advantages for Energy Storage Battery

1. Partial state of charge (PSOC)

A partial state of charge is not a good option for lead-acid batteries. Lead-acid batteries do not perform well when they are not charged correctly. In that case, lithium-ion batteries are the best choice that can perform well even during the Partial state of charge. Melasta batteries can work properly, even in their charging state.

2. Capacity usage compression

Typical Lead-acid batteries are bigger in size but less energy density as compared to Melasta Li-ion batteries. Melasta batteries provide 100% of their rated capacity with a very less self-discharge rate. These batteries have a longer life cycle with high sustainability and reliability.

3. High efficiency

Melasta batteries are highly efficient, with a rate of 99% in respect of charging and discharging. These batteries have little resistance, which helps to charge much faster as compared to the traditional Lead-acid batteries. Lead-acid batteries only can reach the 60% of their capacity and have a meager recharging rate.

4. Longest Life cycle

Melasta has designed its batteries according to the high-tech standards and produces in state of the art factories equipped with the latest technologies. So our batteries’ life is 10 times longer than normal lead-acid batteries. Melasta batteries still provide 80% to 85% of the rated capacity after using the 2000 cycles. So it minimizes the replacement of your batteries for your appliances.

5. Maintenance Free

The best thing about Melasta Li-ion batteries is that they do not need any maintenance, no watering, no corrosion. The self-discharge rate is very low for Melasta batteries; they do not lose their capacity during their idle state; this characteristic can assure the availability of energy whenever you need it.

6. Green Energy

Melasta produces all the batteries according to International safety and green environment standards and does not use any hazardous material which can affect the natural environment. We are proud to provide green energy to the world.
