Sunpro 5070/48V

India's rural households and farms face two simultaneous costs: power cuts that stop the pump, and electricity bills that drain the budget. The Invertek Sunpro 3670 solves both.

Runs 1HP Submersible Pump on Solar

Starting a 1HP submersible pump requires 3,000–3,500W of inrush current for the first second. The Sunpro 3670's 2500W rated output and high-surge capacity handles this reliably — drawing water during solar hours at zero electricity cost.

The Farm Calculation

1HP pump motor draws ~750W running current. Operating 6 hours on solar = 4.5 kWh/day of free pumping. At ₹7/unit agricultural tariff: saving ₹31.50/day = ₹945/month = ₹11,340/year in pump running cost alone. Add household load savings and the Sunpro 3670 pays for itself in under 18 months in most agricultural settings.

AI Solar Intelligence for Agricultural Use

Automatically prioritises pump operation during peak solar hours (10 AM–3 PM) when output is maximum. Charges batteries in parallel. Switches to household load in the evening when pump is not needed. Full automation — no manual management required.

Runs 1.5HP Pump with Proper Panel Sizing

With 6×300W panels (1800W total), the Sunpro 3670 can run a 1.5HP pump motor during peak solar hours (11 AM–2 PM). Recommended for serious agricultural applications with larger water requirements.

What batteries does this inverter require?
The Rapid+ 3500/24V requires 2×12V tubular batteries connected in series (24V system). Recommended capacity is 150Ah to 200Ah for optimal backup.

Is this compatible with lithium battery?
Yes, lithium compatibility depends on the BMS. Please confirm with support.

What appliances can I run simultaneously?
You can run fans, lights, Wi-Fi router, TV, and small appliances depending on total load.

How do I claim warranty?
You can contact Invertek customer support with your purchase invoice to initiate warranty service.

Does it work during low voltage (brownouts)?
Yes, it is designed to operate efficiently even during low voltage conditions.

What is the changeover time? Will my PC restart?
The changeover time is less than 8ms, so sensitive devices like PCs usually do not restart.

Is installation included?
Installation support may be provided depending on your location. Please confirm with customer care.
