Quick answers about our inverters, batteries, net metering, installation and support.
Fronus designs and manufactures solar hybrid inverters (IP65 and IP21), on-grid inverters, three-phase commercial systems, LiFePO₄ lithium batteries, and monocrystalline solar panels. All products are engineered in Pakistan for local grid and climate conditions.
No. Fronus is a Pakistani solar manufacturer headquartered in Lahore. We design our own products, write our own firmware, and operate our own service network. We are not an OEM rebrand: every circuit board and firmware version is designed by our engineering team.
Fill in the contact form on our website or call 042-111-111-140. Our team will ask about your monthly electricity bill, load requirements, and roof space to size the right system. Consultations are free with no obligation.
Fronus does not provide installation, transportation, or any other on-site services. These arrangements are the customer's responsibility.
Fronus products are available through our 200+ authorized dealers across Pakistan. Visit our contact page or call us to find the nearest dealer in your city.
IP65 inverters are weather-proof (rated for dust and water jets), so they can be installed outdoors directly on a rooftop without any enclosure. IP21 inverters are indoor-rated, ideal for installations where indoor mounting is available. Both offer hybrid functionality with battery support.
Yes. Fronus hybrid and on-grid inverters are NEPRA-compliant and support net metering. The firmware is specifically tuned for Pakistan's grid requirements and net metering policy.
IP21 Hybrid Inverters come with a 1-year warranty, while IP65 Hybrid Inverters come with a 5-year warranty. Warranty claims are handled at any of our 16 service centers nationwide.
Yes. Fronus IP65 hybrid inverters support parallel operation and battery expansion. You can add more solar panels (up to the inverter's MPPT capacity) or additional lithium batteries as your energy needs grow.
Fronus uses LiFePO₄ (lithium iron phosphate) cells, the safest and longest-lasting lithium chemistry for solar storage. Our batteries offer 6,000 to 8,000 plus cycles, meaning approximately 15+ years of daily use.
Fronus LiFePO₄ batteries are rated for 6,000+ cycles at 80% depth of discharge. With daily cycling, that translates to 15–20 years of operational life. We offer a 5-year warranty on all lithium batteries.
Fronus batteries use standard 48V communication protocols and can technically work with compatible third-party inverters. However, for optimal performance and warranty coverage, we recommend pairing with a Fronus hybrid inverter or consult with our technical team.
Fronus lithium batteries range from 2.56 kWh to 15 kWh in a single unit. Multiple units can be connected in parallel for larger storage requirements. Wall-mount and rack-mount options are available.
Net metering is a NEPRA policy that allows solar system owners to export excess electricity back to the grid. Your electricity meter runs backwards when you generate more than you consume, effectively giving you credit on your bill.
Your solar installer typically handles the net metering application with your local DISCO (e.g. LESCO, FESCO, K-Electric). The process involves submitting your system design, getting a generation license from NEPRA, and installing a bidirectional meter.
All Fronus on-grid and hybrid inverters are NEPRA-compliant and support net metering. The on-grid range is specifically designed for pure grid-tied operation, while hybrid inverters add battery backup on top of net metering capability.
Savings depend on your system size, electricity tariff, and consumption pattern. A typical 10 kW system can reduce a Rs. 25,000–40,000 monthly bill by 70–90%.
A residential solar system (3–10 kW) typically takes 1–2 days to install. Commercial systems (15 kW+) may take 3–5 days depending on complexity. This excludes the net metering approval process.
If you choose a Fronus IP65 inverter, no. It can be installed outdoors directly on your rooftop or exterior wall. IP21 inverters should be installed in a ventilated indoor location away from direct rain and dust.
Solar panels can be installed on concrete roofs (most common in Pakistan), metal/tin roofs, and tiled roofs. The mounting system varies by roof type. Your installer will assess structural suitability during the site visit.
Fronus has 17 service centers across Pakistan including Lahore, Karachi, Islamabad, Peshawar, Multan, Faisalabad, Gujranwala, and more. Visit our Service Centers page for the full list and directions.
Most warranty claims are resolved within 3–7 business days at your nearest service center. Fronus handles all warranty claims directly, with no middlemen and no finger-pointing between brands and distributors.
