Solar PCU (Power Conditioning Unit); Model - Sunmagic

Solar Bidirectional PCU

With electricity getting expensive and other power sources disappearing due to over use, solar power proves to be the right option that can provide electricity for household as well as commercial premises purposes without worrying about the increased electricity bill. With bidirectional solar inverters you can achieve this and be your own electricity provider. Enertech UPS – the leading name among MPPT Solar grid feed PCU manufacturers offers its range of bidirectional solar inverter to choose from.

Enertech bidirectional solar inverter SunMagic model uses special MPPT based charger to boost maximum energy from PV modules to charge batteries and also supply to the load at the same time. Enertech being an indigenous MPPT solar bidirectional inverter manufacturer uses advanced DSP based technology to be able to share solar power with battery power to produce the required output to drive load. Battery discharge capacity can be configured using a buffer backup technology. In case of weak batteries output of the solar grid feed pcu is kept constant with another unique feature of mains sharing. The MPPT charger rating is designed to a capacity of delivering current to load as well as charging batteries. The bidirectional solar inverter is capable to provide priority charging and also provide buffer backup in battery in case of unavailability of mains supply.

Being a bidirectional solar inverter under the condition of battery low the grid charger becomes active which drives the load and also charges the batteries to a preset level so that in the morning when solar energy resumes, further charging is done by using the renewable energy option. Enertech bidirectional solar inverter offers a PF of more than 0.95. SunMagic also called as solar grid feed inverter delivers power back into the grid in cases of load not absent and battery full. The solar grid feed inverter is utilized for net-metering facility to earn incentives based on government policies.

Solar PCU for netmetering can benefit many industries, offices and regular house hold users to sell power at differential rate governed under local authority. Netmetering is concept implemented to promote use of solar power which acts as a solar generator and a source to earn revenue.

Manufactured as per ISO guidelines, these solutions come with protection against overload, short circuit and reverse polarity for the battery. All these indications are provided on a user friendly LCD screen.

In case the solar power is not sufficient to charge batteries, additional power from grid is derived to maintain charging levels of battery. Once the battery is fully charged the load is automatically shifted on Inverter and this is one of the top reasons why Enertech is being the preferred choice amongst all MPPT solar inverter manufacturers.

All our systems come with an inbuilt isolation transformer making it extremely rugged to face critical environmental conditions. Enertech is one of the few solar off grid inverter manufacturers which have been accredited by IEC-61683 for efficiency test and IEC-60068 for environmental tests. Our products are also approved by MNRE.

Enertech an indigenous mppt solar bidirectional inverter manufacturer has its service setup throughout India with offices in major cities like Pune, Mumbai, Bangalore, Hyderabad, Chennai,Cochin, Delhi, Coimbatore, Vizag, Bhopal & Ahmedabad etc.

The company also exports power solutions to several African, UAE and Asian countries.
