4095W - 48V Off Grid Solar Kit - 3kVA RiiOSun-II - All in One

4095W – 48V Off-Grid Solar Kit with 3kVA RiiO Sun II All-in-One Inverter

The 4095W 48V Off-Grid Solar Kit with RiiO Sun II all-in-one inverter from Sunshine Solar is a high-capacity solar power package designed to generate renewable electricity and store energy for use when sunlight is limited. It combines nine high-efficiency 455W N-type TOPCon bifacial solar panels, a 3kVA RiiO Sun II inverter/charger with integrated MPPT solar charge controller, and a 48V 105Ah lithium battery.

This 4.095kW solar panel kit is designed for suitable off-grid applications, including remote homes, cabins, workshops, garden offices, summer houses, static caravans, stables and outbuildings. It can help provide electricity where mains power is unavailable or where a correctly designed solar and battery system is needed to reduce reliance on an external electricity supply.

The all-in-one RiiO Sun II combines several essential power management functions in one unit, including solar charging, battery charging, DC-to-AC power conversion and automatic transfer functionality for supported AC input arrangements.

With the main solar, inverter, battery and connection components supplied together, this kit offers a starting point for a 48V off-grid solar installation. The system must still be configured and installed correctly for the intended electrical loads and site conditions.

Nine 455W N-Type TOPCon Bifacial Solar Panels

The kit includes nine Sungrow SG-48TG4D 455W N-type TOPCon bifacial solar panels, providing a combined nominal rated capacity of 4095W (4.095kW).

N-type TOPCon technology is designed for efficient solar electricity generation. The bifacial design allows the panels to capture light from both the front and rear surfaces, potentially improving energy generation where the mounting arrangement and surrounding surfaces provide useful reflected light.

Key solar panel specifications include:

• Rated power: 455W per panel.
• Number of panels: 9.
• Combined nominal array capacity: 4095W.
• Cell technology: N-type TOPCon bifacial.
• Stated maximum module efficiency: 22.8%.
• Construction: Dual glass with a black-anodised aluminium alloy frame.
• Junction box protection: IP68.
• Maximum system voltage: 1500V DC, subject to the module specification and system design.
• Stated warranty: 25-year product warranty and 30-year linear performance warranty for the specified panel model.

Actual solar generation depends on location, season, weather, panel orientation, tilt, shading and system losses. Bifacial gains vary according to the amount of reflected light reaching the rear of the panels.

RiiO Sun II 3kVA All-in-One Inverter and MPPT Controller

The RiiO Sun II 3kVA 48V inverter/charger is the central power management component of this kit. It combines several functions in one enclosure to help simplify the design of a compatible off-grid solar installation.

Pure sine wave inverter

The inverter converts DC electricity from the battery and solar system into AC electricity for compatible appliances. The available AC output is limited by the inverter's rated power and surge capability.

Before connecting equipment, check the power consumption and starting current of appliances such as pumps, refrigerators, freezers, power tools and other motor-driven loads.

Integrated MPPT solar charge controller

Maximum Power Point Tracking (MPPT) technology regulates the solar panel input to help harvest available energy as sunlight and panel operating conditions change.

Correct solar panel string design is essential. The array must operate within the inverter's permitted PV voltage, current and power limits.

Battery charger and automatic transfer functionality

The RiiO Sun II incorporates battery charging and automatic transfer functionality for supported AC input configurations. Depending on the installation, a compatible external AC source may be used alongside solar generation and battery storage.

The exact operating mode depends on the inverter configuration, connected equipment and manufacturer instructions. Grid connection and export arrangements must be checked separately against applicable requirements.

System monitoring and control

The included E4 LCD monitor provides a local interface for monitoring and controlling the compatible RiiO Sun II system. Supported remote monitoring features may also be available when the required connectivity and configuration are in place.

Monitoring can help users understand system operation, charging activity and energy use.

Included 48V 105Ah LiFePO4 Lithium Battery

This kit includes one TBB ES100 48V 105Ah lithium iron phosphate (LiFePO4) battery for energy storage.

The battery has a nominal stored energy capacity of approximately 5.04kWh, calculated from its nominal voltage and amp-hour rating. The energy available to appliances will be lower after allowing for battery operating limits, inverter losses and other system conditions.

The ES100 battery includes an integrated battery management system (BMS) designed to provide protection against conditions such as overcharging, excessive discharge, overcurrent and abnormal temperature.

Lithium iron phosphate batteries are used in many stationary energy storage and off-grid applications. The battery must be installed and configured in accordance with the manufacturer's instructions and compatibility requirements for the inverter.

Is one 105Ah battery enough?

Whether the included 105Ah battery is sufficient depends on how much electricity you use and when you need it. It may provide useful storage for selected loads, but it will not necessarily support high consumption throughout the night or through several days of poor weather.

When planning your system, consider:

• The daily electricity consumption of your appliances in kWh.
• How much electricity you need to store for evening and overnight use.
• The maximum simultaneous load and any appliance starting surges.
• The battery manufacturer's recommended charging and discharge limits.
• Whether additional compatible battery capacity is required.

The RiiO Sun II platform supports system expansion in compatible configurations, but any expansion must follow the inverter and battery manufacturer's specifications. Do not assume that additional batteries can be connected without checking the required configuration, communications and protection.

Expected Summer Solar Performance

Sunshine Solar lists an indicative summer performance figure of approximately 341Ah per day on a 48V system for this kit.

This is an estimate, not a guaranteed daily output. Actual performance varies with the season, local weather, sunlight hours, panel angle, shading, temperature, battery charging conditions and system losses. Winter generation in the UK can be considerably lower than summer generation.

Amp-hours (Ah) measure electrical charge relative to a system voltage. They should not be interpreted as a fixed quantity of usable electricity without considering voltage, battery storage, conversion efficiency and operating conditions.

For a realistic system assessment, estimate your daily electricity use in kWh and compare it with expected solar generation for your location. Consider battery capacity separately to determine how much energy can be stored for use when solar generation is low.

Where Can You Use the 4095W Off-Grid Solar Kit?

This kit may suit a variety of installations where the solar array, inverter and battery storage are correctly sized for the intended loads.

• Remote homes and cabins: Generate solar electricity where a mains connection is unavailable or difficult to install.
• Garden offices and workshops: Supply electricity for compatible lighting, computers, tools and other equipment within the inverter's output limits.
• Summer houses and outbuildings: Provide solar generation and battery storage for buildings with suitable panel installation space.
• Static caravans and leisure properties: Support compatible electrical loads in an appropriately designed off-grid installation.
• Stables and rural buildings: Supply power for selected lighting and equipment where the system is suitably designed.
• Backup-power projects: Form part of a system designed to support selected loads when an appropriate backup arrangement is installed.
• Off-grid energy storage: Store solar energy for later use, subject to the battery's capacity and the system's operating limits.

The kit's suitability depends on your electricity requirements, appliance starting currents, battery storage needs, installation location and the availability of other power sources.
