Itel Power Tank 1000 + 2 JA 625W Solar Panels: specifications and details

PRE-ORDER — SHIPPING STARTS 10 OCTOBER 2026 This is a pre-order bundle. Actual shipping starts on 10 October 2026. BUNDLE CONTENTS • 1 × itel Power Tank 1000 (IESS-1K20N): 1000W pure sine wave AC output and 2000Wh LiFePO4 battery. • 2 × JA 625W bifacial solar panels (catalogue model: JAM78D40-625/MR). • Total panel nameplate capacity: 1250Wp (2 × 625W). This is the combined solar-panel rating; the Power Tank remains a 1000W-output unit with a published 1200W PV input rating. PRODUCT OVERVIEW Itel Power Tank 1000 — IESS-1K20N An integrated household energy system with adaptive power control, combining an inverter, battery and MPPT controller in one unit. It brings energy storage and solar charging together for everyday backup power. The inverter supplies AC electricity from stored battery energy. The charge controller manages energy coming from solar panels. Keeping these functions together makes this a practical option to consider for essential household electronics. AC POWER AND APPLIANCE COMPATIBILITY • Output: 1000W, pure sine wave • Apparent power (maximum): 1200VA • AC: 230V, 50/60Hz Watts (W) describe how much power appliances draw while running. Add together the ratings of the devices you want to use at the same time. Lights, televisions, routers, phone chargers and laptops can be suitable choices when their combined demand stays within the output rating. Motor-driven appliances may need considerably more power when starting. Check both running and starting requirements before connecting them. The VA figure is an apparent-power rating, not an additional allowance of continuous watts. BATTERY CAPACITY AND SERVICE LIFE • Storage: 2000Wh (2kWh), Class-A lithium iron phosphate (LiFePO4) • Charge-cycle rating: 6000+ • Supplier projections: up to 10 years; up to 2 hours under heavy loads Watt-hours (Wh) measure stored energy. They help estimate how long a load can run; they do not increase the inverter’s power limit. Battery service-life projections describe expected use rather than a warranty period. Actual backup time depends on the combined appliance load, available charge, battery condition and conversion losses. Using fewer devices or lower-power lighting can extend the time between charges. CHARGING OPTIONS • Charging: solar, grid, or both • Supplier’s combined-charge estimate: approximately 2 hours Dual charging means using two energy sources together. Treat a stated charging time as an estimate: available input power, the battery’s starting charge and any appliances drawing power during charging affect how quickly the battery refills. SOLAR INPUT AND MPPT • PV limit: 1200W; 60V maximum • Tracking range: 11–60V • Input-current limit: 30A • Startup: 11V • Trackers: 1 • MPPT efficiency: 99.0% • Battery-mode conversion: 86.0% maximum PV means photovoltaic, or solar-panel, input. MPPT means Maximum Power Point Tracking: the controller adjusts its electrical operating point to draw useful power from the panels as conditions change. Panel selection involves more than wattage. The complete panel arrangement must also meet the stated voltage and current limits. Series and parallel connections change those electrical values. The MPPT and battery-conversion figures describe different stages, so they should not be treated as the same measure of efficiency. GRID INPUT • Operating range: 90–280V AC • Bypass input: 1000W maximum • Voltage withstand: 380V The operating range is the range intended for normal use. A withstand figure describes tolerance under a specified condition; it is not a normal supply-voltage setting. USB AND DC CONNECTIONS • USB-C1/USB-A1: 5V/3A or 9V/2A; 20W total • USB-A3/USB-A4: 2.5A combined • DC5525: 12V/4A Match a device’s required voltage, connector and power demand to its chosen output. Where a rating is shared, connected devices draw from that combined allowance rather than each receiving the full total. BACKUP TRANSFER • UPS transfer: under 20ms Transfer time is the brief interval when backup equipment changes power sources. A short transfer can help electronics continue operating through a power cut. Whether a particular device stays on also depends on how much interruption its own power supply can tolerate; this is not a zero-transfer-time specification. SIZE, WEIGHT AND COOLING • Dimensions (W×H×L): 300 × 300 × 180mm • Weight: approximately 19kg • Cooling: intelligent fan • Noise: below 45dB (Silent); below 50dB (Performance) BUILT-IN PROTECTIONS • Grid/PV overvoltage • Overload • Short circuit • Overtemperature • AC Type-II surge protection JA 625W BIFACIAL SOLAR PANELS Each panel is rated as follows under standard test conditions: • Maximum power: 625W • Voltage at maximum power (Vmp): 46.37V • Current at maximum power (Imp): 13.48A • Open-circuit voltage (Voc): 55.49V • Short-circuit current (Isc): 14.36A • Module efficiency: 22.4% Bifacial panels can collect light from both sides. Actual output depends on sunlight, temperature, mounting position and rear-side illumination. Nameplate ratings describe standard test conditions rather than a guaranteed constant output. SOLAR CONFIGURATION AND INSTALLATION The proposed two-panel arrangement is parallel, not series. At standard test conditions, two matching panels in parallel have 1250Wp total nameplate power, 46.37V operating voltage, 26.96A operating current, 55.49V open-circuit voltage and 28.72A short-circuit current. The array rating is 50W above the Power Tank’s published 1200W PV rating. Acceptance of this array oversizing and the allowable PV short-circuit current must be confirmed with itel before installation. Rear-side gain, electrical tolerances and cold-weather open-circuit voltage must be included in that check. No manufacturer approval of this pairing is claimed here. Do not connect these two panels in series: their combined nominal open-circuit voltage would be 110.98V, above the Power Tank’s 60V maximum. Installation must use the correct manufacturer-approved PV connector, cable sizing and protection. The listed bundle contents are the Power Tank and two panels. Installation services, mounting hardware and any additional wiring are not specified as included.
