The PYTES Energy V16 is a high-capacity 51.2V wall-mounted LiFePO4 battery built for residential and light commercial energy storage. With 16 kWh of energy, strong continuous and surge output, and long cycle life, it’s designed to support daily solar cycling and heavy backup loads. It features a rugged outdoor-ready cabinet, self-heating for cold-weather charging, and advanced safety systems, while offering seamless closed-loop integration with many mainstream inverters. The V16 can be installed on a wall or ground-mounted and scaled in parallel for larger storage banks.

High 16 kWh storage capacity – 51.2V, 314Ah battery provides substantial energy for longer runtimes and bigger backup needs.
Long-life LiFePO4 chemistry – Lithium Iron Phosphate cells deliver safer operation and an extended lifespan compared to traditional lithium or lead-acid.
Strong continuous power delivery – Supports 125A continuous charge/discharge (about 6.4 kW) for steady everyday loads.
High surge capability – Handles up to 300A peak discharge for 15 seconds to cover appliance startup spikes.
Scalable up to 16 units in parallel – Expand your system up to 16 batteries (up to 256 kWh total) without needing a dedicated hub.
Seamless inverter integration – Closed-loop communication support via multiple ports for strong compatibility with many inverter brands.
Built-in fire suppression safety – Integrated aerosol fire suppression system adds protection inside the battery enclosure.
ESS emergency shutdown ready – Includes an emergency shutdown function to support safer system control during faults.
Durable IP66 enclosure – Sealed protection against dust and water for rugged indoor or sheltered outdoor installs.
