Marstek Venus D All-in-One Battery & Inverter
Code: MARSTEK-VENUS-D
Product detailed description
The Marstek Venus D is a powerful all-in-one energy storage system (ESS) designed for modern residential and balcony solar applications. Featuring four independent MPPT inputs, it maximizes solar generation from multiple orientations, capturing up to 4000W of PV input with outstanding efficiency. Its 2.5kW bidirectional inverter enables intelligent energy flow—charging the battery when electricity is cheap and powering your home when demand or prices rise.
Built for reliability and flexibility, the Venus D offers backup power up to 2.5kW (3kW peak) with ultra-fast <15 ms EPS switching, ensuring uninterrupted power for essential loads. The modular battery design allows expansion from 2.56kWh up to 15.36kWh, while multiple units can be combined (with SmartBox) for larger home energy solutions.
Powered by MARSTEK Intelligence (AI), the system learns your energy usage patterns, weather conditions, and solar production to optimize self-consumption and reduce electricity costs. With seamless plug & play installation, robust LFP battery technology, and full system control via the MARSTEK app, the Venus D offers a smart, durable, and future-ready energy solution.
