Off-Grid Solar Package 7.65kWp 7.2kW

The A2Z 7.65kWp 7.2kW Off-Grid Solar Package is designed for residential, agricultural and remote commercial sites requiring a substantial independent energy supply with 230 V single-phase output. The official package combines 18 TommaTech 425 Wp 108TN M10 TOPCon solar panels, one M Plus 7.2 kW MPPT smart inverter and four 51.2 V 100 Ah modular LFP batteries.

The solar array provides 7.65 kWp of nominal capacity across a published module area of 35.28 m². The battery bank provides 20.48 kWh of nominal storage, with the official source publishing 18.432 kWh as available energy using a 90% depth-of-discharge assumption. Under CW Enerji's illustrative four-sun-hour calculation, the array corresponds to 30.6 kWh/day of nominal solar production before real-world system losses.

This capacity level is suitable for off-grid homes, farmhouses, field offices, security and communication sites, smaller workshops and rural businesses with controlled load profiles. It may support everyday refrigeration, lighting, office electronics and selected household appliances, but final suitability depends on simultaneous demand, starting currents, seasonal solar conditions and the required number of autonomy days.

Official Appliance-Use Examples

The official package catalogue presents the following illustrative scenario using Türkiye's annual-average four-hour daily sunshine assumption:

• 1 x A++ energy-class refrigerator: 48 hours
• 1 x A-class washing machine at 30°C: 4 hours per day
• 1 x A-class dishwasher in economy mode: 4 hours per day
• Laptop computer: 24 hours, excluding peripherals
• 1 x 60-inch LCD/LED television: 12 hours
• 10 x 5 W LED lamps and 10 x 11 W energy-saving lamps: 24 hours
• 1 x vacuum cleaner: 3.5 hours
• Four each of mobile-phone, toy, MP3 and radio charging loads: described by the source as unlimited-time charging

These examples must be presented as the manufacturer's illustrative package scenario, not as a promise that every load can operate simultaneously or for the same duration at every site. Appliance efficiency, duty cycle, battery state of charge, weather, season and system losses materially affect results.

Component Highlights

Solar module: The current official TT425-108TN10 sheet publishes 425 Wp peak power, 21.76% module efficiency, 32.14 V maximum-power voltage, 38.31 V open-circuit voltage, IP68 junction-box protection, 1,722 x 1,134 x 30 mm dimensions and 21.45 kg module weight.

Inverter: The exact TT-MPLUS 7.2KW-48V reference provides 7.2 kW pure-sine-wave output, MPPT charging, built-in Wi-Fi, BMS communication, selectable AC/PV priorities and compatibility with a correctly integrated utility or generator input.

Battery: The official TT-MDL-48V-100AH manual publishes 51.2 V, 100 Ah and 5,120 Wh per battery, CAN/RS485 communication, IP65 protection and parallel operation up to 16 units. The package uses four batteries and must retain the package-specific power and communication arrangement.

Important Installation, Selection, Quotation and Safety Notes

• Prepare a 24-hour load schedule before selection. Record appliance power, daily operating time, simultaneous loads and the starting current of every motor, compressor, pump or transformer-based device.
• This is a 230 V single-phase package. Do not quote it for three-phase machinery or three-phase building distribution without a separately engineered solution.
• The official 9x2 string arrangement is a source design reference, not a substitute for site engineering. Recalculate string Voc at the project's minimum design temperature and verify MPPT voltage, connector polarity, cable current and protection requirements against the exact modules and inverter supplied.
• Using the current TT425-108TN10 values, one nine-module string is approximately 289.26 V at Vmp and 344.79 V at Voc under STC. Temperature correction and manufacturing tolerance must still be applied before installation.
• The official 30.6 kWh/day value is based on four hours of sunshine and nominal module power. Do not present it as guaranteed delivered energy; include temperature, shading, inverter, cable, battery and availability losses in the project yield model.
• The published 18.432 kWh available-energy value uses a 90% DOD assumption. It is not the same as usable AC energy after inverter and wiring losses and does not by itself establish overnight autonomy.
• Confirm required autonomy for cloudy weather, seasonal low-production periods and critical loads. A generator or other backup source may be required for continuity-sensitive sites.
• The inverter platform supports a utility or generator input, but source ratings, changeover behaviour, neutral/earth arrangement, charging current and protective devices must be designed for the site.
• Mounting structures, roof or ground-mount hardware, DC combiner/protection, fuses, breakers, isolators, surge protection, AC distribution, earthing, lightning protection, cable containment, civil works, installation and commissioning are not identified in the official package BOM. Confirm and quote each item separately.
• The official BOM lists 75 one-metre units of red and 75 one-metre units of black 6.00 mm² solar cable. Verify route length, voltage drop, conductor sizing and any additional cable requirement for the actual site.
• Install batteries in accordance with the exact battery manual. Use the specified battery-power, parallel and communication cables; configure the master/slave and BMS communication arrangement correctly.
• Installation, commissioning and maintenance must be completed by competent personnel using the current manuals and locally accepted protective practices.
• Before international shipment, confirm the current component revisions, destination-country conformity requirements, lithium-battery transport documentation, packaging and after-sales support arrangements.
• Obtain written confirmation of the final supplied BOM before quotation because the package catalogue is an official 2023-2024 document and the current component download centre includes newer product generations.

Product-Specific Source Reconciliation

• The live product page says “Laptop Computer (24 Days Excluding Peripherals)”. The official package catalogue says “For 24 Hours Excluding Peripherals”. Use 24 hours and do not publish “24 days”.
• The live product page repeats “LFP Lytum Battery Parallelling Cable Set” twice. The official package catalogue resolves the second three-piece line as Battery to Battery Communication Cable. The package contents above follow the catalogue.
• The live page describes an A+++ refrigerator, while the catalogue extraction shows A++. To avoid an unsupported efficiency-class promise, treat the example as an illustrative efficient-refrigerator scenario or confirm the intended class with CW Enerji before publishing it verbatim.
• The exact package code appears in the official package catalogue, not on the current live product page. Keep OFP-7.2KWE-48V-18P exactly as written.
• Confirm whether the supplied panel remains TT425-108TN10, because the live BOM uses a family description while the current 425 Wp technical sheet provides the exact model reference.
