On Grid Solar System Without Export :
Grid Independence: Batteryless solar UPS systems allow for the direct utilization of solar power without the need for battery storage. This reduces the overall cost and maintenance requirements associated with batteries. It enables users to rely primarily on solar energy during the day, minimizing their dependence on the grid.
Cost Savings: Battery systems add significant upfront costs to solar installations. By eliminating the need for batteries, batteryless solar UPS systems can be more cost-effective and accessible for users. They provide an alternative for individuals or businesses who want to benefit from solar power but have budget constraints.
Export Limitation: In some regions, grid regulations may limit or prohibit the export of excess solar power back to the grid. Batteryless solar UPS systems with zero export capability ensure that no surplus energy is fed back to the grid, thereby complying with local regulations. This feature can prevent any penalties or restrictions imposed by utility companies.
Grid Sharing: Certain batteryless solar UPS systems also offer grid sharing functionality. This means that when solar power production is insufficient to meet the load demand, the system can automatically draw additional power from the grid to supplement the requirements. This ensures a consistent and reliable power supply, especially during periods of low solar irradiation
Solar Smart Hybrid Home UPS :
This is just one of its kind Solar Hybrid UPS available in India with true current sharing between Grid and Solar most effectively and efficiently. It has a micro controller based PWM Charge Controller which can handle upto 20A charging current. When the Solar is available, the grid power will not be used for battery charging or for the load. Load works from Solar power. Mains will be used only when the battery voltage is below a preset voltage (adjustable). When mains is on, Solar and Mains do not load each other like in other UPSs, but the charging is done with the intelligently shared current. An outstanding feature is that if the UPS gets overloaded while working on Solar, the load gets shifted to Mains, automatically. Again when the Battery charge reaches a preset high level, Mains is cut off and the load gets shifted to Solar/battery.
Capacities available are 400, 700, 900 & 1100VA in 12V and 1.6kVA & 2.2kVA in 24V. The Open Circuit Voltage is 110% more than the system DCV and the Vmpp range for 12V is 14-18V & for 24V, it is 28-36V. The maximum panel wattage that can be connected to a 12V system is 400W and to a 24V system, it is 800W.
The output is pure Sinewave and all other regular features in a Home UPS is available in this as well. Our proprietary features such as Hot swappability of batteries, SMPS charger on mains and anti MOSFET blast lock and our famed ‘safest short circuit protection’ etc also are incorporated.

On Grid PCU with MPPT Charger (GPCU) :
When you need to rely solely on solar power, or for high-power applications such as solar power plants, this rugged and intelligent PCU is ideal. Equipped with an MPPT charge controller with over 95% efficiency, it optimally manages input sources – Solar, Battery, Grid power / DG – for economical and application-friendly operations. It supports critical loads using an Online topology, ensuring smooth functioning across any situation.
The most fascinating feature of this PCU is that when solar is available, the grid doesn’t get switched off but grid power is also not used for charging or for load. And batteries do not get discharged when solar is available. Solar charges the batteries and also powers the load. When solar is not available, you have a choice of using the mains or battery. Battery capacity could be very low, if you do not want to store the power.
The DC input to the MPPT can be between +20% and +50% of the system DCV. The Vmpp per panel is between 13 & 19V and the open circuit voltage is two and half times the Nominal Voltage. The maximum Charging current that can be set is 40A which covers all normally possible battery capacities. LCD displays all MPPT parameters and all state of the art protections are provided for smooth functioning and long life.
The Grid (Mains) charger is also highly efficient because it is Power Factor Corrected (IGBT Rectifier). GPCU is available from 48VDC to 360VDC and from 1kVA to 100kVA capacities. Pure sine wave output and galvanic isolation between i/p & o/p are other features that make this PCU, a true winner.
