3640W - 48V Off/On Grid Solar Kit - 3KVA Victron - All in One

3640W 48V Off/On-Grid Solar Kit with 3kVA Victron EasySolar-II GX – All-in-One Solar Power System

Product Overview

The Sunshine Solar 3640W 48V Off/On-Grid Solar Kit with 3kVA Victron EasySolar-II GX is a solar power solution designed for properties and locations that need renewable electricity, battery storage and the flexibility to integrate with a compatible external AC power supply.

Combining a high-output solar panel array with Victron Energy's integrated inverter/charger and MPPT solar charge controller, this all-in-one system brings several essential solar power functions together in a single unit. It may be suitable for appropriately designed installations in cabins, workshops, garden offices, outbuildings and other properties where conventional mains electricity is limited or solar power is intended to supplement an existing supply.

The kit is designed around a 48V battery system and includes AGM battery storage. The Victron EasySolar-II GX combines solar charging, inverter/charger functionality and system monitoring to simplify system integration and everyday management.

Key Benefits of the 3640W Victron Solar Kit

• 3640W solar array: Designed to generate electricity from sunlight for immediate use and battery charging.
• 48V battery system: A higher-voltage battery configuration suitable for appropriately designed off-grid and hybrid installations.
• 3kVA Victron Energy inverter/charger: Converts battery power into AC electricity and supports charging from a compatible external AC source.
• Integrated MPPT solar charge controller: Helps optimise the transfer of available solar energy into the battery system.
• All-in-one design: Combines key power conversion and solar charging components in one integrated Victron unit.
• AGM battery storage: Stores surplus solar energy for use when solar generation is reduced.
• System monitoring: The integrated GX platform provides access to system information, with supported monitoring and configuration options.
• Versatile applications: Can be considered for suitable cabins, workshops, garden offices, remote buildings and solar backup installations.

How Does the 3640W 48V Solar Kit Work?

The solar panels generate DC electricity when exposed to sunlight. The integrated MPPT charge controller regulates solar charging, directing available energy towards the connected 48V battery bank. The Victron inverter/charger then converts battery DC electricity into AC power for compatible appliances and electrical equipment.

Where the installation includes a suitable grid or generator connection, the inverter/charger can also manage charging from that AC source. The exact operating mode depends on the system configuration, installation and applicable electrical requirements.

Battery storage allows energy collected during daylight hours to be used later, including in the evening or during periods of reduced solar production. Actual performance depends on sunlight, season, panel orientation, shading, battery condition, electrical loads and conversion losses.

Victron Energy EasySolar-II GX – Integrated Solar Control

At the heart of this kit is the Victron Energy EasySolar-II GX 48V 3000VA system. It integrates three key functions:

Inverter/Charger

The inverter converts stored battery energy into AC electricity for compatible equipment. Its charger function can charge the batteries from a suitable AC input, such as a compatible mains or generator supply.

The 3kVA rating describes the inverter's apparent-power capacity. It should not automatically be treated as a continuous 3kW usable load in every operating condition. Check the manufacturer's output specifications and consider appliance starting currents before selecting equipment.

MPPT Solar Charge Controller

Maximum Power Point Tracking (MPPT) technology continually adjusts the operating point of the solar array to harvest available energy efficiently under changing conditions. Correct panel-string design and compliance with the controller's voltage and current limits are essential.

GX Monitoring and Control

The integrated GX device provides system information and control functions. Depending on the installation and connectivity, users can access relevant solar, battery and inverter/charger information through supported display and monitoring options.

Solar Panels and AGM Battery Storage

The solar array is rated at 3640W nominal capacity. This represents the panels' combined rated power under standard test conditions, not a guarantee of the electricity they will generate every day. Actual output varies with weather, daylight hours, panel orientation, shading, temperature and installation conditions.

The kit includes AGM battery storage to retain energy for use when solar generation is low. Total storage capacity in kWh depends on the battery models and their configuration. Battery capacity, usable energy and expected runtime should be confirmed from the product's exact bill of materials and battery specifications.

For the best results, size the system around your daily electricity consumption, peak loads and the amount of backup time required. Lead-acid battery systems also require suitable charging settings and careful management to support battery life.

Where Can This Solar Kit Be Used?

The 3640W 48V Victron solar kit may be suitable for a range of applications, subject to correct system sizing and installation.

• Cabins and remote properties: Generate and store solar electricity where a standard mains connection is unavailable or limited.
• Garden offices and workshops: Supply power for compatible lighting, computers, tools and other equipment within the system's capacity.
• Outbuildings and rural buildings: Support electrical loads where a suitably designed solar installation is practical.
• Solar and battery backup: Work alongside a compatible AC supply to provide battery charging and inverter power.
• Hybrid solar installations: Combine solar generation, battery storage and a suitable grid or generator input when configured for the intended application.

Before purchasing, check that the inverter's output, the battery bank's usable capacity and the solar controller's limits are appropriate for your appliances and expected usage.

Before ordering, confirm the exact panel specification, battery capacity, included protection and cabling, and the intended grid or off-grid operating mode. These details will help ensure the kit matches your energy requirements.

Technical note: Product contents and specifications should be checked against the current Sunshine Solar listing and manufacturer datasheets before installation or publication.
