Energy Storage Solutions for Solar Installers

Start with the amount of energy the load needs and the required backup time. A simple estimate is: Required battery capacity (kWh) = Daily or backup energy demand (kWh) ÷ Usable battery depth of discharge ÷ System efficiency. For example, if a site needs 10 kWh of usable energy, the lithium battery supports 90% DoD, and overall system efficiency is about 90%, the required nominal capacity is approximately 12.3 kWh.

All Anern product series support communication compatibility with mainstream third-party inverter brands, including Pylontech, Growatt, Risen Energy, Pengcheng, SRNE, Victron, GoodWe, Deye, Solis, and other leading inverter manufacturers.

Low-voltage batteries typically operate around 48V or 51.2V and are commonly used in residential, small commercial and off-grid solar systems. They are relatively simple to configure and can suit projects that prioritize straightforward installation and broad hybrid-inverter compatibility. High-voltage batteries use multiple modules connected in series to create a higher system voltage and are more common in larger residential, commercial and C&I solar-plus-storage applications. At higher power levels, the higher voltage can reduce current and cable losses. Choose the voltage architecture around the inverter, power level, project scale and scalability requirements.

Model-specific installation manuals are provided for each product, covering wiring diagrams, cable sizing, circuit breaker specifications and essential safety precautions.

Yes. Anern can support off-grid solar installations with configurable LiFePO4 battery storage solutions for locations where grid power is unavailable, unstable or insufficient. Depending on the project, the system can integrate solar panels, lithium batteries, inverters and optional generators. For project evaluation, provide the load demand, solar capacity, inverter model, backup-hour requirement and installation environment so the battery capacity, voltage platform and system configuration can be assessed.
