High-Efficiency 455W N-Type TOPCon Bifacial Solar Panels

The kit includes eight 455W N-type TOPCon bifacial solar panels, providing a combined nominal array capacity of 3640W (3.64kW).

N-type TOPCon solar technology is designed for efficient electricity generation. The bifacial panel design can also capture reflected light reaching the rear surface, potentially increasing generation where the mounting arrangement and surrounding surfaces allow it.

Key panel features include:

• 455W rated output per panel.
• Eight panels with a combined rated output of 3640W.
• N-type TOPCon bifacial cell technology.
• Black-anodised aluminium alloy frames.
• Dual-glass construction.
• Up to 22.8% stated module efficiency.
• IP68-rated junction box.
• Stated 25-year product warranty and 30-year linear performance warranty for the specified panel model.

Actual output depends on sunlight, location, season, temperature, orientation, shading and installation conditions. Any additional benefit from bifacial generation depends on the amount of reflected light reaching the rear of the panels.

Victron Energy EasySolar-II GX: Inverter, Charger and MPPT in One Unit

The Victron Energy EasySolar-II GX combines key solar power functions in one integrated enclosure, reducing the need to install separate inverter, charge controller and monitoring units.

Inverter/charger

The inverter converts DC electricity from the battery system into AC electricity for compatible appliances and equipment. The charger can also charge the battery bank from a compatible AC input, such as a suitable mains or generator supply.

The inverter's rated output determines how much AC power can be supplied at a given time. Check the exact model's continuous output, peak output and surge capability before connecting appliances with high starting currents.

Integrated MPPT solar charge controller

Maximum Power Point Tracking (MPPT) technology adjusts the operating point of the solar array to help harvest available solar energy as sunlight and panel conditions change.

The solar panel string configuration must comply with the charge controller's permitted voltage and current limits. Correct system design is essential for safe and reliable operation.

GX monitoring and control

The integrated GX device provides access to relevant information from the compatible inverter/charger and solar charge controller. Depending on the configuration and available connectivity, users can view system information and use supported monitoring and control features.

The included Victron BMV-712 Smart Battery Monitor provides additional information about battery status and energy use when correctly installed and configured.

AGM Battery Storage for a 48V Solar System

This version of the kit includes four 110Ah, 12V AGM deep-cycle sealed batteries. When configured in series as intended, four 12V batteries form a nominal 48V battery bank with a capacity of approximately 110Ah.

The nominal stored energy is approximately 5.28kWh before accounting for usable depth of discharge, inverter losses and other system limitations.

AGM batteries are a type of sealed lead-acid battery designed for a range of leisure, backup and energy storage applications. Their usable capacity and service life depend on discharge depth, charging settings, temperature and the wider system configuration.

When choosing a solar battery system, consider:

• Your average daily electricity consumption in kWh.
• The appliances you need to run simultaneously.
• How much electricity you need to store for evening and overnight use.
• The expected periods of low solar generation.
• The manufacturer's recommended charging and discharge limits.

The nominal battery capacity does not mean that all stored energy should be used on every cycle. Follow the battery manufacturer's recommendations to help protect battery life.

How Does the 3640W Off/On-Grid Solar Kit Work?

During daylight hours, the solar panels generate DC electricity. The integrated MPPT charge controller regulates the solar input and directs available energy towards the battery system and supported power-conversion functions.

The inverter/charger converts DC power into AC electricity for compatible equipment. When configured with a suitable external AC source, the system can also support battery charging from that source.

The battery bank stores energy for use when solar production is reduced, including during the evening. The amount of electricity available depends on solar generation, battery condition, usable battery capacity, system losses and the electrical load.

Important: The term “off/on-grid” does not automatically mean that every installation can export electricity to the public grid. Grid connection, backup operation and export capability depend on the system configuration, local requirements and appropriate installation and approval.

Where Can You Use This Victron Solar Kit?

This 3640W solar kit may be suitable for a range of applications where the system is correctly designed for the property's energy requirements.

• Remote homes and cabins: Generate and store solar electricity where a conventional mains connection is unavailable or limited.
• Garden offices and workshops: Supply electricity for suitable lighting, computers, tools and other equipment within the inverter's output limits.
• Summer houses and outbuildings: Create a solar power system for buildings with suitable space for panels and batteries.
• Static caravans and leisure properties: Provide solar generation and battery storage for compatible installations.
• Rural buildings and stables: Support selected electrical loads where a correctly designed system is appropriate.
• Hybrid solar installations: Combine solar generation and battery storage with a suitable AC input when the system is configured for that purpose.
• Selected backup-power applications: Support compatible loads when an appropriate backup configuration is installed.

Before choosing a kit, check the maximum expected load, appliance starting currents, daily energy demand, battery storage requirements and the available space for solar panels.

How Much Electricity Can a 3640W Solar Kit Generate?

The 3640W rating describes the combined nominal output of the solar panels under standard test conditions. It is not a guarantee that the system will generate 3640W continuously or produce a fixed amount of electricity each day.

Solar generation varies with UK weather, season, daylight hours, panel orientation, tilt, shading, temperature and system losses. Winter production can be substantially lower than summer production.

For an accurate estimate, consider the installation location, panel layout and expected daily electricity consumption. Battery storage should then be sized to suit the amount of energy needed when solar production is low.
