Miumaeov 1400W Grid-Tie Solar Microinverter — MPPT Pure Sine Wave DC-to-AC 110V, IP65 Waterproof

Overview Durable aluminum-alloy construction makes this Miumaeov inverter resistant to corrosion and wear for long-term use. Designed as a grid-tie microinverter, it converts DC to AC and outputs a clean pure sine wave at 110V while incorporating MPPT for optimal solar harvesting. Performance and Control - High efficiency: unique circuit topology, imported industrial components and an isolated high-frequency transformer deliver efficiency greater than 99% and stable maximum power point tracking. - Digital control: combines intelligent soft-switching, high-frequency switching power supply technology and 32-bit DSP full digital SPWM control technology for fast response, strong anti-interference capability and advanced functionality. Electrical Safety and Cooling - Full electrical isolation between input and output improves overall insulation and safety; the fully isolated booster circuit increases reliability. - Thermal design uses a self-cooling system plus heat-dissipation openings to reduce operating temperature, lower safety risks and extend service life. Protections and Environmental Rating Six built-in protections include over-temperature protection, under-voltage alarm, under-voltage protection, over-voltage protection, short circuit protection and overload protection. The unit carries an IP65 waterproof rating to guard against rain and outdoor exposure. Installation and Form Factor Compact footprint at 8.27*1.57*14.72inch; the inverter employs high-frequency telephone, micro processing and related technologies to remain small and lightweight. Multiple units can be stacked to create single-phase parallel arrays or combined into three-phase systems. A detailed manual and accessories are supplied for straightforward installation. Maintenance After the power station is installed, routine maintenance is minimal—periodically clear dust from the photovoltaic panels is typically all that’s required. Important Notes and Recommendations - Install according to the instructions and do not disassemble the unit; only qualified maintenance personnel should perform repairs. - Mount the inverter in a well-ventilated, low-humidity location and keep it away from flammable or explosive materials. Keep children away to prevent electric shock. - This inverter does not include a monitoring function. It is grid-connected: the AC output must be tied into the home grid for grid-tied generation to work. - When the input is from solar panels, the VOC must be between 30-48V. We recommend sizing solar array capacity about 20% above the inverter rating. For example: if the product is 600W, total panel power should be between 700-750W; if the product is 1200W, total panel power should be between 1200-1400W. - When using a battery input, recommended battery voltage is 36V (can be achieved with three 12V batteries in series). Do not reverse polarity when connecting. Recommended battery current: 36V/10mah for 300W, 36V/20mah for 600W, and 36V/40-45mah for 1200W. - Ensure input and output voltages fall within the product’s normal operating range for proper grid connection.
