While this shift can increase monthly electricity costs for unmanaged systems, it also creates an opportunity. Solar paired with intelligent battery storage allows users to actively control grid dependence, reduce peak-hour consumption, and optimize energy costs. Growatt’s SPE and WIT hybrid inverter platforms are designed to help Indian customers convert TOU challenges into measurable savings.

Why TOU Matters for Indian Consumers
Under TOU billing structures, electricity tariffs vary across the day — typically lower during solar-rich daytime hours and significantly higher during evening or industrial peak periods. Smart meters capture real-time consumption and peak demand with greater accuracy, making short-duration load spikes far more expensive than before.
This new billing reality demands smart energy management, not just solar generation. Hybrid inverter systems with advanced control logic now play a central role in reducing electricity bills and improving energy predictability.

SPE Series: Smart TOU Control for Homes & Small Businesses
The Growatt SPE Series Hybrid Inverters are tailored for Indian residential and small commercial users who face rising tariffs, voltage fluctuations, and frequent outages.
Under smart-meter and TOU conditions, the SPE Series delivers:
· Solar-first energy usage, ensuring daytime loads are powered directly by PV to reduce grid draw during high-tariff periods
· Intelligent battery charging during low-tariff or high-solar hours, with discharge during peak pricing windows
· Feed-to-grid power control, helping users comply with utility export limits while maximizing net-metering or feed-in benefits
· Peak load support, minimizing sudden grid demand spikes that can inflate monthly bills
With flexible operating modes such as Solar First (SOL), Solar & Battery (SBU), and Solar & Utility (SUB), SPE systems automatically manage energy flow without user intervention. Real-time monitoring through the ShinePhone App enables users to track consumption, generation, and battery performance, maximizing self-consumption and cost savings.

WIT Series: Industrial-Grade Optimization for C&I Facilities
For factories, warehouses, and commercial facilities impacted by demand charges and TOU penalties, the Growatt WIT Series hybrid inverters provide a powerful cost-control advantage.
Key benefits under TOU billing include:
· Peak shaving and demand control, where batteries discharge during peak tariff windows to reduce recorded maximum demand
· Time-based energy arbitrage, storing energy during low-cost periods and deploying it when grid power is expensive
· Reduced diesel generator dependency, optimizing DG runtime and lowering fuel and maintenance costs
· High-capacity scalability, supporting large PV and battery systems suitable for industrial operations
With intelligent coordination between solar, batteries, grid, and generators, WIT systems transform energy storage into a predictable financial asset rather than a backup-only solution.

One Platform for India’s Evolving Grid
Across both SPE and WIT platforms, Growatt offers:
· Integrated PV + battery + load management in a single system
· TOU-ready scheduling aligned with Indian tariff structures
· Compatibility with net-metering, self-consumption, and future regulatory changes
· Robust performance under Indian grid and climate conditions
As smart meters and TOU tariffs become the norm, energy systems must do more than generate power — they must adapt, respond, and optimize.
With Growatt SPE for homes and small businesses and Growatt WIT for commercial and industrial users, customers are equipped to stay ahead of India’s evolving energy landscape while reducing costs and improving energy reliability.
