Solar + Battery Hybrid
For commercial sites where solar alone cannot cover after-sunset energy or continuity needs. The design balances PV size, usable battery energy, charge window and reserve.
PCS + BESS
For larger C&I systems where dedicated battery PCS architecture, scalability and higher control flexibility are more appropriate than a standard hybrid inverter.
Smart EMS Integration
Coordinate energy sources and operating limits through metering, communication, scheduling, reserve logic and system-level monitoring.
Emergency Energy Support — Roadmap
Planned reserve-energy service for compatible sites using controlled DC-to-DC energy transfer, with customer-site energy delivery designed to operate independently of the customer inverter/PCS during the transfer.
Hybrid inverter or dedicated PCS?
There is no universal “better” choice. The right architecture depends on system scale, PV relationship, battery power, control flexibility, redundancy and the selected OEM ecosystem.
Hybrid inverter architecture
- PV and battery functions are commonly integrated in one platform.
- Can simplify system architecture for suitable commercial applications.
- Useful where selected inverter capacity, MPPT design and battery interface match the site.
- Final design depends strongly on OEM model limits and supported operating modes.
PCS + BESS architecture
- Battery power conversion is separated from the PV inverter architecture.
- Can provide more flexibility for larger storage systems and staged expansion.
- Useful where battery power, independent control or system-level integration drives the design.
- Requires careful coordination of PCS, BMS, EMS, AC bus, protection and communication.
Evidence first. Equipment second.
The same kW load can require very different energy systems depending on runtime, demand profile, solar availability and business priorities.
Understand consumption, tariff and time-of-day behaviour.
Record actual machines, operating schedule and critical loads.
Decide hybrid inverter vs PCS and PV/battery relationship.
Check OEM datasheets, electrical limits, protection and compatibility.
Reserve energy should be a service, not an improvised connection.
Samvora’s planned continuity model combines reserve inventory, mobile service equipment, BMS-controlled charging and measured energy delivery.
Battery DC → controlled DC/DC → customer battery
- No uncontrolled direct battery paralleling.
- BMS charge permission, voltage/current limits and interlocks remain active.
- Customer inverter/PCS is not required for the emergency DC transfer path.
- Delivered kWh is metered at a defined service boundary.
Dedicated reserve + tariff-referenced support
- Initial pilot reserve planning: around 25% of active deployed storage.
- Reserve level is recalculated from reliability and turnaround evidence.
- Emergency energy pricing is intended to be materially below the prevailing grid variable charge.
- Example direction only: ₹15/kWh grid reference → approximately ₹6–₹7/kWh target.
Beyond headline capacity numbers.
Final project engineering should validate the actual selected equipment and site conditions.
Battery energy & power
Usable DoD, reserve, C-rate, charge time, discharge requirement and lifecycle assumptions.
PV compatibility
Module electrical values, MPPT limits, string design, generation assumptions and site constraints.
Protection & SLD
Breaker/fuse sizing, cable ratings, metering, isolation, earthing and system single-line architecture.
Have a high electricity bill or large daytime load?
Start with a first assessment before committing to a battery or inverter size.
