Frequently Asked Questions

Tall Tubular Batteries use a tubular plate technology that offers significantly longer life (4–8 years), better efficiency, and lower maintenance compared to flat plate batteries. They perform exceptionally well in Kerala's climate with high temperatures and frequent deep discharge cycles.

We offer an industry-leading 36-month warranty on our Tall Tubular Batteries. During this period, any manufacturing defect is covered at no cost to you. Our service team will inspect and replace faulty units promptly.

The right capacity depends on your load and backup requirement. As a general guide: 75Ah gives 3–4 hours backup for basic loads; 100Ah gives 5–6 hours; 150Ah gives 8–10 hours. We offer free consultation to calculate the exact size for your home — contact us.

For Tall Tubular Batteries, check water levels every 2–3 months during summer and every 4–6 months during winter. Only use distilled or DM water — never tap water. Keep the level between the MIN and MAX marks.

A Pure Sine Wave inverter produces power identical to the grid — clean, stable AC power. It is essential for sensitive appliances like refrigerators, air conditioners, medical equipment, laptops and LED TVs. Our PowerOn Smart 1500 is a pure sine wave inverter, making it safe for all home appliances.

In UPS Mode, the inverter switches to battery within milliseconds of a power cut — so fast that computers, routers and sensitive devices do not even notice the outage. This is ideal for home offices and study areas.

Our Smart 1500 inverters carry a 24-month manufacturer warranty. Any defect covered during this period is repaired or replaced at no cost. Extended warranty options are available — ask us for details.

Grid-Tied systems are connected to the electricity grid. Excess solar power is exported to the grid earning you credits (net metering). They do not have battery backup — power cuts affect them. Off-Grid systems are standalone with batteries — ideal for remote locations or areas with frequent power cuts. Hybrid combines both: solar + battery + grid connection.

Under the PM Surya Ghar scheme, Kerala homeowners can get: 30% subsidy up to 2 kW and 20% for additional capacity up to 3 kW. For a 3 kW system, the subsidy can be ₹48,000+. We handle all MNRE subsidy paperwork and applications on your behalf.

Given Kerala's high electricity tariffs and good solar irradiation, most homeowners recover their investment in 3–5 years. With the government subsidy, payback can be as low as 2.5 years. After that, you enjoy free solar electricity for 20+ years.

Yes — modern monocrystalline panels generate electricity even under diffused/cloudy light, typically at 20–50% of peak output. Kerala averages 4.5–5.5 peak sun hours per day even accounting for monsoon seasons, making solar highly viable throughout the year.

Yes! PowerOn Technologies serves all 14 districts of Kerala — from Thiruvananthapuram in the south to Kasaragod in the north. Call +91 90611 55953 to schedule a visit to your location.

For batteries and inverters, same-day or next-day installation is typically available. For solar systems, installation takes 2–5 days depending on system size and roof assessment. Emergency installations for battery failures can be arranged within hours.

An Annual Maintenance Contract (AMC) ensures your battery, inverter, or solar system is serviced regularly by our technicians. Benefits include: scheduled inspections, priority emergency service, discounted repairs, and extended product life. We highly recommend AMC for commercial setups and solar systems.
