Overview
VersaVane is a family of MPPT solar pump drives and controllers exclusively designed for solar water pumping applications as per MNRE specifications. It is available in the range of 1 HP to 10 HP and is compatible with AC Induction Motor (ACIM) and Permanent Magnet Synchronous Motor (PMSM) pump sets used in agricultural, rural and community water systems.
The drive sits between the solar PV array and the submersible or surface pump and converts DC from the panels into a controlled 3-phase AC supply for the pump. VersaVane continuously tracks the maximum power point of the PV array, delivers high inverter efficiency and incorporates pump-specific algorithms such as water-flow estimation, pump unclogging and dry-run protection.
For OEMs and system integrators, VersaVane is available as:
- A complete solar pump drive
- An IP-rated solar pump controller
- A PCBA for integration into existing IP65 enclosures and systems
Key Features
- MPPT solar pump controller family – designed specifically for solar water pumping applications as per MNRE specifications, covering 1–10 HP pump sets.
- ACIM and PMSM compatibility – supports both AC induction and PMSM pump sets, enabling OEMs to standardise on a single solar pump controller family across different motor technologies.
- High MPPT and inverter efficiency – MPPT efficiency better than 98% (dynamic) and 99% (static) with inverter efficiency > 96%, ensuring maximum utilisation of available solar energy.
- Sensorless vector control for PMSM – advanced sensorless vector control for PMSM pump motors, delivering smooth starting, good low-speed torque and stable operation without external position sensors.
- Pump-specific protections and algorithms – built-in dry-run and low-water protection, pump unclogging routine to clear debris, soft start and controlled ramp-up to reduce mechanical stress, and overload protection.
- Water-flow estimation without sensor – on-board water-flow rate calculation algorithm estimates flow from electrical and operating parameters, eliminating the need for a separate flow sensor in many systems.
- Remote monitoring and communication – supports Remote Monitoring Units (RMU), Bluetooth (optional on certain variants) and RS485 (MODBUS) communication, allowing real-time monitoring and integration into OEM portals.
- Multiple hardware options for OEMs:
- Solar Pump Drive – panel-mounted drive with RMU support and optional Bluetooth.
- Solar Pump Controller – IP65-rated controller with in-built RMU and reverse polarity protection.
- PCBA – board-level controller with reverse polarity protection, MODBUS support and 24 V auxiliary supply for RMU integration, customisable to fit existing IP65 enclosures.
- Standards and compliance – designed to comply with relevant IEC standards for environmental tests, EMC and drive efficiency (including IEC 60068-2, IEC 61800-3, IEC 61683 and IEC 61000-6-3:2006, model-dependent).
Applications
- Agricultural solar water pumping – submersible borewell and surface pumps for irrigation.
- Rural and semi-urban drinking-water schemes – village-level and community water supply systems.
- Lift irrigation and canal-based pumping schemes powered by solar PV.
- Solar retrofit of existing AC pump installations (where compatible motors are used).
- Other off-grid or weak-grid water pumping applications where solar power is preferred.
