Firman offers some of the most competitive warranties in the Nigerian energy sector:
  • Solar Panels: 12-Year Product Warranty (materials & workmanship) and a 25-Year Linear Power Output Warranty.
  • Lithium Batteries (LiFePO4): 6-Year Full Warranty.
  • Hybrid Inverters: 2-Year Full Warranty.
  • Commercial & Industrial (C&I) Systems: 5-Year Comprehensive System Warranty.
This is a common point of confusion for solar panel buyers:
  • Product Warranty (12 Years): Covers physical defects, such as a frame corroding, glass shattering due to heat, or internal connection failures.
  • Performance Warranty (25 Years): Guarantees that the panels will still produce at least 80–85% of their original rated power after 25 years of use.
To keep your warranty valid, you must avoid these "Void Conditions":
  • Natural Disasters: Damage from lightning strikes (without a surge protector), floods, or extreme storms.
  • Improper Installation: Damage caused by non-certified installers (e.g., reverse polarity or poor cable sizing).
  • Physical Abuse: Dropping the unit, cracked screens, or "man-made" damage.
  • Unauthorized Repairs: Opening the inverter or battery casing by anyone other than a Sumec Firman authorized technician.
Registration is mandatory for service.
  1. Keep Your Receipt: Your original purchase invoice is your primary proof.
  2. Warranty Card: Ensure the installer fills out the warranty card included in the box.
  3. Online Registration: Visit the official portal (or torrent.ng if purchased through them) to upload your serial number and installation date within 10 days of purchase.
f you suspect a fault, follow this process:
  • Step 1: Do not return the unit to the retail store immediately.
  • Step 2: Contact the Firman Service Desk (or Torrent Power support) for "Remote Troubleshooting." Many "faults" are simply configuration errors.
  • Step 3: If the hardware is faulty, you will be issued a Case Number.
  • Step 4: Take the unit to the nearest Sumec Firman Service Center (Lagos, Abuja, Onitsha, or Port Harcourt).
No. Under the standard policy, the cost of transporting the faulty unit to the service center and back is the responsibility of the owner. However, if you have an Annual Maintenance Contract (AMC) with Torrent Power, on-site service may be included.
No. A replacement unit carries the remainder of the original warranty period. For example, if your 6-year lithium battery is replaced after 2 years, the new battery will have 4 years of warranty remaining.
The standard Firman factory warranty covers the repair or replacement of the hardware (parts and labor at the service center). It generally does not cover the "call-out fee" for a technician to travel to your site for de-installation.
  • Pro Tip: If you purchased a complete package from an authorized dealer like Torrent Power, your installation agreement may include a "Workmanship Warranty" which covers site visits for the first 6–12 months.
Most people think a 25-year warranty means the panels work like new for 25 years. In reality, it is a Linear Performance Guarantee:
  • Year 1: Maximum 2–3% degradation.
  • Years 2–25: Maximum 0.5%–0.7% degradation per year.
  • Result: Firman guarantees that by Year 25, your panels will still produce at least 80.7% of their original rated power. If they drop to 60% in Year 10, you have a valid warranty claim.
Yes, Firman Hybrid inverters are "open" and compatible with most Lead-Acid, Gel, and LiFePO4 batteries. However, if a non-Firman battery malfunctions (e.g., leaks or shorts out) and damages the inverter, the inverter warranty will not cover the repair. Using a full Firman-to-Firman setup is the only way to ensure 100% "system-wide" coverage.
In Nigeria, the Firman warranty is typically tied to the original purchaser and the original installation address. If you move the system to a new house or sell it to a third party, you must notify the authorized distributor to inspect and "re-verify" the system to keep the warranty active.
If a component (like a specific 5kW inverter model) is discontinued and fails under warranty, Firman will replace it with the nearest equivalent model with the same or better specifications. Your remaining warranty period will simply transfer to the new unit.
Yes! Modern Firman Hybrid inverters and Lithium batteries have internal logs. If the system displays a critical fault code (e.g., "F52" for Bus Voltage High or "BMS Communication Error"), you should photograph the screen. This digital proof makes the claim process much faster at the service center.
Firman Hybrid inverters have built-in protection, but they are not invincible. If your generator's AVR fails and sends 400V into a 230V inverter, the "burnt board" will be visible to technicians. This is often classified as "External Electrical Surge" and may be excluded from free warranty repair.
  • Solution: Always ensure your system includes an external AC Surge Protector and a Voltage Sensitive Relay (VSR) to act as a shield.
The best way to determine the size is through a professional Site Inspection and load calculation. A 3.5KW system is typically ideal for small offices and apartments, while 5KW to 11KW systems are engineered for larger luxury homes and industrial applications.
Yes! Torrent Power offers "Inverter System Installation" as a standalone service. If your grid (PHCN) supply is decent, we can set up the inverter and batteries first to provide immediate backup, and you can integrate Firman solar panels whenever you are ready.
Standard installations within Lagos typically take 2–3 business days. For installations outside Lagos, the timeframe is usually 5–7 business days.
  • Lithium (LiFePO4): These are modern, maintenance-free, and come with a 6-year warranty. They offer a much longer lifespan (over 6,000 cycles).
  • Tubular (TP2500): These use Calcium technology and are designed for deep discharge recovery with a 24-month warranty. They are a cost-effective alternative but require more space than lithium.
Keep the inverter and batteries in a dry, well-ventilated area. Use the system regularly rather than leaving it idle for long periods, and ensure you do not exceed the recommended load for your specific battery capacity.
All Firman panels are high-efficiency Mono Half-Cut modules. The choice depends on your available roof space. The 610W panel offers the highest efficiency (22.8%) and is ideal if you have limited space but need maximum power output.
Yes, Firman panels are designed to maintain high performance even in low-light and low-temperature conditions, though output will be lower than on a full sunny day.
  • Inverters: 2 Years
  • Lithium Batteries: 6 Years
  • Solar Panels: 12 Years (Manufacturing defects) / 25–30 Years (Linear power output)
  • C&I Energy Storage (Large Scale): 5 Years
The warranty covers defects in materials and workmanship. It does not cover damage from improper installation (if not done by a certified professional), unauthorized repairs, electrical surges, or natural disasters.
Torrent Power offers regular system checks to ensure your panels are clean and producing maximum output, your inverter is charging correctly, and your battery terminals are in good condition.
  • Yes, but it depends on the capacity. High-capacity inverters (5KW to 11KW) are designed to handle heavy inductive loads like ACs, refrigerators, and pumping machines. Our team will help isolate these loads correctly during installation.

During installation, we divide your Distribution Board (DB) into "Essential" (Solar/Inverter) and "Heavy" (Grid/Generator only) loads. This ensures you don't accidentally drain your batteries by running heavy appliances like water heaters on solar power.
During the peak Harmattan season (November to March), dust can reduce efficiency by up to 30% in just one week. We recommend rinsing your panels with water every 2 weeks during this period.
No. Standard detergents can leave a thin film that attracts more dust. Use only clean water and a soft microfiber cloth or squeegee. If you have stubborn bird droppings, use a mild, pH-neutral soap only on that spot.
Yes, but pumping machines have a very high "starting current" (surge). We recommend at least a 5KW Firman Hybrid Inverter for standard 1HP pumps. It is best to pump water during the day when the sun is out to preserve battery life.
This usually happens because the fridge's "surge" exceeds the inverter's capacity. Firman Hybrid inverters feature a Peak Power rating (e.g., a 5KW unit can handle a 10KW peak for a few seconds) to prevent this. If it still trips, you may need to upgrade your inverter or use a "soft-start" device on your fridge.
Absolutely. The ZERO C100 is designed for "off-grid" primary use. It can be programmed to prioritize Solar power during the day, Battery at night, and Grid/Generator only as a last resort.
The internal cooling system is powered by the system itself to ensure the Lithium cells stay between 20°C and 25°C, which is critical for maintaining the 10-year lifespan in Nigeria's heat.
MPPT (Maximum Power Point Tracking) is an electronic system that optimizes the match between the solar array and the battery bank. A Firman MPPT controller can improve your solar harvest by 20–30% compared to older PWM controllers.
Yes. Firman Hybrid Inverters have an AC-Input port. You can plug your generator into the inverter, and the inverter will "clean" the power, charge your batteries, and pass through power to your house without the typical voltage fluctuations of a generator.
In Nigeria, especially during the rainy season, lightning is a major risk. Every Firman installation should include a DC Surge Protective Device (SPD) for the solar panels and an AC SPD for the inverter to prevent high-voltage spikes from damaging the motherboard.
