When pairing this high-capacity power station with Tier-1 solar panels, one of the top commercial and technical queries searched on Google Nigeria is: “Can I use Longi 620W solar panels with Itel Power Tank 1000W?”
Matching high-efficiency Tier-1 solar modules with an integrated portable power station requires careful verification of open-circuit voltage (V_{oc}), MPPT operating window, and parallel vs. series wiring rules so you never risk over-voltage damage. In this comprehensive Google Nigeria buyer and installation guide, we break down the exact datasheet specifications, wiring rules, and wholesale market prices verified by CEO Mr. Joseph Chikeleze of Nature Solar Global Enterprises.
Direct Answer: Can I Use Longi 620W Solar Panels With Itel Power Tank 1000W?
Yes—you can safely and optimally use Longi 620W solar panels (as well as equivalent Tier-1 Jinko or JA Solar 620W Half Cut Bifacial Solar Panels) with the flagship 1000W/2000Wh Itel Power Tank (Model IESS-1K20N). In fact, pairing 620W x2 (1,240W total nominal solar capacity) is the recommended PV capacity to fully saturate the unit’s built-in 1,200W MPPT solar charge controller under real-world Nigerian sunshine and rooftop heat.
However, there is one mandatory installation rule every buyer and solar technician must follow:
- You MUST connect the two Longi 620W solar panels in PARALLEL (using MC4 Y-Branch parallel connectors).
- You must NEVER connect two Longi 620W solar panels in SERIES, because series wiring doubles their open-circuit voltage (~104V to 107V DC), exceeding the Itel Power Tank’s 60V DC maximum solar input limit.
When wired properly in parallel, “Can I use Longi 620W solar panels with Itel Power Tank 1000W?” is an unqualified YES, delivering ultra-fast 2-to-3-hour solar charging and reliable backup power without risking controller damage.
Technical Compatibility Breakdown: Longi 620W Bifacial Panel vs. Itel Power Tank 1000W Specs
To see exactly why Longi 620W modules match the 1000W/2000Wh Itel Power Tank so cleanly, compare the verified manufacturer datasheets of both products side by side:
1. Itel Power Tank 1000W/2000Wh (Model IESS-1K20N) Specifications
- System Design: Compact All-in-One Solar Generator integrating a pure sine wave inverter, MPPT solar charge controller, and lithium battery bank inside a portable 19kg unit (300mm × 300mm × 180mm).
- Inverter Output Rating: 1000W inverter output (Pure Sine Wave continuous load, delivering clean, grid-grade AC electricity safe for Smart TVs, laptops, standing fans, Starlink routers, and inverter refrigerators).
- Battery Capacity & Chemistry: 2000Wh/2KWH Battery powered by automotive-grade LiFePo4/Lithium Battery Powered cells rated for 6,000+ deep cycles (8 to 12+ years of daily Nigerian use).
- Maximum Solar (PV) Input Rating: 1,200W Max PV Input (620W x2 recommended PV capacity).
- MPPT Operating Voltage Window: 11V – 60V DC (60V DC absolute maximum Open-Circuit Voltage limit).
- AC Grid / Generator Input Tolerance: 90V – 280V AC wide voltage range, allowing fast dual charging even during low-voltage NEPA/PHCN supply
2. Longi 620W Half-Cut Bifacial Solar Panel Electrical Ratings (STC)
Depending on the specific Longi Hi-MO 620W N-Type / HPBC double-glass bifacial model stocked in Nigeria (such as Longi Hi-MO 6 / Hi-MO 7 / Hi-MO X6 620W), the Standard Test Condition (STC) ratings are:
- Rated Maximum Power (P_{max}): 620W (plus up to 10%–25% rear-side bifacial reflection gain).
- Open-Circuit Voltage (V_{oc}): ~52.2V to 53.5V DC.
- Maximum Power Operating Voltage (V_{mp}): ~43.8V to 45.2V DC.
- Short-Circuit Current (I_{sc}): ~14.6A to 15.1A.
- Maximum Power Operating Current (I_{mp}): ~13.7A to 14.2A.
3. Why Parallel Wiring Guarantees 100% Electrical Compatibility
- In Parallel (2 × Longi 620W): Open-circuit voltage remains equal to a single panel (~52.2V to 53.5V DC), sitting safely below the 60V DC ceiling even during cool Harmattan mornings in Northern Nigeria. Meanwhile, the operating voltage (V_{mp}) stays at ~43.8V to 45.2V DC—right inside the sweet spot of the 11V–60V DC MPPT tracking window. Combined array wattage equals 1,240W, and the built-in smart MPPT controller automatically regulates incoming amperage up to its 1,200W charging cap without overheating.
- In Series (2 × Longi 620W — STRICTLY PROHIBITED): Connecting the two panels in series doubles the open-circuit voltage to ~104.4V – 107.0V DC, blowing past the 60V DC ceiling and causing permanent MPPT controller failure that voids your 2-year warranty.
Side-by-Side Comparison: Parallel vs. Series Wiring for Two Longi 620W Panels

| Official Warranty Protection | 100% Valid (2 Years) | Voided by Over-Voltage | 2 Years Official Warranty |
Why Longi, Jinko, or JA Solar 620W Half-Cut Bifacial Panels Beat Mono-Facial Panels in Nigeria
When buying 620W x2 solar panels for your 1000W/2000Wh Itel Power Tank, selecting Tier-1 Longi, Jinko, or JA Solar Half Cut Bifacial Solar Panels instead of traditional mono-facial panels provides major performance advantages across Nigerian climates:
- Bifacial vs. Mono-Facial Dual-Sided Power Harvest: Unlike conventional mono-facial panels with opaque backsheets that only absorb light from the front, a Bifacial Solar Panel uses transparent dual-glass construction to capture direct sunlight on the front while simultaneously absorbing reflected sunlight bouncing off your aluminum or zinc roof from underneath. In Lagos, Port Harcourt, Calabar, Ibadan, and Abuja, bifacial gain generates 10% to 25% more daily electricity, helping your 2000Wh/2KWH Battery reach 100% charge even during overcast or rainy weather.
- Half-Cut Cell Architecture for Shade & Heat Resilience: Half Cut cells split standard solar cells into two independent halves, lowering internal resistance and preventing hotspot overheating. If a tree branch, satellite dish, or dust layer covers the bottom half of one panel, the top half continues producing 50% power instead of shutting down the entire string.
- Superior Low-Light & Tropical Heat Performance: Authentic Longi, Jinko, and JA Solar 620W modules feature an ultra-low temperature coefficient, maintaining stable voltage and high charging wattage even when afternoon roof temperatures reach 45^\circ\text{C}–55^\circ\text{C} in Kano, Maiduguri, Abuja, and Enugu, while excelling during early morning and late afternoon hours.
What Appliances Can the 1000W/2000Wh Itel Power Tank Run in Nigerian Homes & Offices?
Once your two Longi 620W bifacial panels recharge the 2000Wh/2KWH LiFePO4 Battery, the 1000W inverter output cleanly powers essential Nigerian home and office loads with zero petrol noise or fumes:
- Home Living Room & Cooling: 55-inch Smart LED TV, DStv/GOtv decoder, soundbar, 2 standing fans, and 8 LED bulbs (~180W–220W load) for 8.5 to 10+ hours.
- Remote Work, Tech Office & Starlink Setup: Starlink dish/router, 2 laptops, external monitor, and rechargeable fan (~130W–150W load) for 12 to 15+ hours.
- Kitchen Refrigeration: Energy-efficient inverter refrigerator or compact inverter chest freezer (under 300W running draw and under 1000W compressor startup surge) for 10 to 13 hours.
- Barbershops, Salons, Clinics & POS Kiosks: Hair clippers, ring lights, POS terminals, desktop computers, thermal printers, and CCTV security systems.
(Important Buying Tip: Avoid plugging heavy resistive heating appliances or high-surge inductive loads exceeding 1,000W continuous draw, such as non-inverter split air conditioners, electric pressing irons, boiling rings, or water heaters.)
