The VaySunic VM800WE-P2 800 W Microinverter is a compact, high-efficiency plug-and-play solution designed for residential and small commercial solar installations using up to two solar panels. Its two independent MPPT channels allow each connected panel to operate individually, helping to improve energy generation when the panels experience different levels of sunlight, shading or soiling.
With a rated AC output of 800 VA, integrated Wi-Fi communication and remote monitoring through the VaySunic VIP Cloud platform, the VM800WE-P2 provides convenient module-level system monitoring and reliable solar energy conversion.
The durable metal enclosure has an IP67 outdoor protection rating and uses fanless natural-convection cooling. The microinverter can operate in ambient temperatures from −40°C to +65°C, making it suitable for year-round outdoor installation in a wide range of weather conditions.
The VM800WE-P2 is supplied as a complete plug-and-play package with a compatible UK AC cable and plug. It can be installed by the consumer without specialist commissioning, provided that the installation instructions, electrical safety requirements and applicable UK regulations are followed.

Independent Dual-MPPT OperationThe VaySunic VM800WE-P2 has two independent MPPT channels, with one solar panel connected to each channel. Each panel is monitored and controlled individually, allowing the microinverter to optimise the output of both modules separately. This can help reduce energy losses when one panel is affected by partial shading, dirt, leaves, different panel orientations or variations in module performance. |
Wi-Fi MonitoringIntegrated Wi-Fi communication allows the microinverter to connect to the VaySunic VIP Cloud monitoring platform. Customers can remotely view system performance, energy generation and the operating status of the connected solar panels. The availability of individual monitoring functions may depend on the system configuration, internet connection, monitoring account and compatible VaySunic equipment. |
Simple Plug-and-Play InstallationThe VaySunic VM800WE-P2 is supplied as a plug-and-play solar solution with a compatible UK AC cable and plug. The system can be installed by the consumer without specialist commissioning, provided that the supplied installation instructions are followed and the solar panels, mounting system, cables and electrical connections are installed safely. The microinverter should be connected only to a suitable outdoor electrical socket and circuit. The customer is responsible for confirming that the socket, electrical circuit and installation location are suitable for the equipment. The installation must be registered with the customer's local Distribution Network Operator (DNO) within 30 days of purchase. The VaySunic VM800WE-P2 is listed on the ENA Type Test Register under reference WUXIX/19818/V1. |
Important Installation InformationBefore installation, check that the voltage, current and power ratings of each connected solar panel are compatible with the VaySunic VM800WE-P2. Each panel must remain within the microinverter's specified operating-voltage, maximum-input-current and maximum short-circuit-current limits. The solar panels and microinverter must be mounted securely in accordance with the relevant product instructions. Cables must be routed and secured so that they are protected from excessive tension, sharp edges, standing water and accidental damage. Where there is any uncertainty regarding the condition or suitability of the household electrical circuit, socket or protective devices, these should be inspected by a qualified electrician before the microinverter is connected. |
The VaySunic VM800WE-P2 is manufactured by VaySunic and sold by Worldwide Solar Ltd as an authorised retail product. Technical specifications and performance values are based on information supplied by the manufacturer. The microinverter is listed on the ENA Type Test Register under reference WUXIX/19818/V1. Actual system output will depend on the connected solar panels, installation location, panel orientation, shading, weather conditions, electrical configuration and other site-specific factors. Product specifications may be changed by the manufacturer without prior notice.
