What is a Solar-to-Power Convertor? How Our Proprietary Technology Eliminates the Need for Batteries
ESSRCPS's patent-pending Solar-to-Power Convertor lets you run 10+ AC appliances directly from solar panels during the day — with zero battery investment. Here's how it works.
When most people think about solar energy, they assume two options: either connect to the grid (on-grid) or store energy in expensive batteries (off-grid). ESSRCPS has developed a third path — the Solar-to-Power Convertor — a proprietary device that changes how daytime solar energy is used, without either grid dependency or battery investment.
The Problem With Conventional Approaches
On-grid systems are cost-effective but useless during grid outages. Most of urban India still faces 2–6 hours of daily load shedding in tier-2 and tier-3 cities.
Battery systems solve the outage problem but add ₹40,000–₹2,00,000 to system costs, require periodic replacement every 3–7 years, and demand careful maintenance.
The gap: Millions of households and small businesses need reliable daytime power — fans, coolers, lights, TVs, motor pumps — but cannot justify battery costs.
What is the Solar-to-Power Convertor?
The ESSRCPS Solar-to-Power Convertor is a direct solar-to-AC conversion unit that:
- Takes raw DC output from solar panels (no battery in between)
- Converts it to stable, regulated 230V AC power
- Supplies this power directly to your appliances during daylight hours
- Automatically switches to grid when solar output drops below load requirement (clouds, late afternoon)
- Disconnects from grid automatically when solar resumes full output
The result is seamless, automatic operation — you don’t need to manually switch anything. Your appliances run on solar during the day and grid during evenings/nights, with the transition invisible to you.
Key Capabilities
10+ Appliance Compatibility
Our convertor supports all standard 230V AC household and commercial appliances simultaneously:
- Ceiling and table fans
- LED and CFL lighting
- Air coolers (evaporative type)
- Televisions and entertainment systems
- Computer systems and printers
- Small pumps and motors (up to 0.5 HP)
- Refrigerators (single-door, energy-efficient models)
- Mixer-grinders and small kitchen appliances
Note: High-inrush appliances like air conditioners, geysers, and large motors require dedicated on-grid or hybrid systems. Our engineers assess compatibility during site visits.

Cost Comparison
A conventional off-grid system for the same daytime load typically costs:
| Component | Conventional Off-Grid | With ESSRCPS Convertor |
|---|---|---|
| Solar panels (2 kW) | ₹60,000 | ₹60,000 |
| Battery bank (C10, 150Ah × 4) | ₹60,000–₹80,000 | ₹0 |
| Inverter + controller | ₹15,000–₹25,000 | ₹25,000 (convertor) |
| Installation | ₹12,000 | ₹12,000 |
| Total | ₹1,47,000 – ₹1,77,000 | ₹97,000 |
Savings: ₹50,000 – ₹80,000 upfront, plus elimination of battery replacement costs every 4–5 years.
Who is This For?
The Solar-to-Power Convertor is ideal for:
- Rural and semi-urban households with frequent daytime load-shedding
- Small shops and establishments requiring daytime power (salons, tea stalls, tailoring shops)
- Agricultural homesteads running daytime pumps and equipment
- Schools and coaching centres that operate primarily during daylight hours
- Any consumer wanting to reduce electricity bills without grid dependency or battery investment
