Solar Battery Storage System Features That Installers Trust
Designed for real-world solar installs — rack-mountable, inverter-compatible, and built to perform in demanding conditions.
Intelligent Battery Management System (BMS)
The integrated BMS provides multi-layer active protection across overcharge, over-discharge, overcurrent, short circuit, and temperature extremes. Cell balancing, SOC/SOH monitoring, and fault diagnostics are communicated in real time via CAN, RS485, and RS232 — giving installers full visibility and reducing after-sales support calls.
Stackable Rack Module — Up to 15 Units in Parallel
The standardized 19-inch rack-compatible form factor (605×383×240mm, 77kg) installs cleanly into server cabinets or purpose-built enclosures. The stackable battery module design eliminates custom racking costs and cuts on-site installation time significantly compared to traditional flat-pack or floor-standing alternatives.
Deep Cycle Performance Across a Wide Temperature Range
Rated for discharge from -20°C to +60°C and charging from 0°C to +60°C, this deep cycle lithium battery performs reliably in garages, utility rooms, and unconditioned spaces across climate zones — from hot Australian summers to cold Central European winters.
Built-In Safety Isolation Switch
Each unit ships with an integrated DC isolation switch, allowing safe manual disconnection during maintenance, commissioning, or emergency shutdown without requiring additional external components or added BoS cost.
Solar Energy Storage System Applications
From single-family homes to multi-unit residential projects, this battery fits the most common solar-plus-storage scenarios.
Residential Solar Self-Consumption
Maximize solar self-consumption by storing excess daytime PV generation and discharging during evening peak demand. A single 10.24kWh unit covers average nightly household loads; stacking 2–4 units supports zero-export and off-grid-capable designs.
Backup Power & Grid Resilience
Provide whole-home backup during grid outages. The high continuous discharge current (up to 120A) and intelligent BMS ensure seamless transition to backup mode — protecting sensitive appliances, home offices, and medical equipment without inverter overload.
Off-Grid & Hybrid Solar Installations
Ideal for remote properties, rural electrification, and hybrid solar systems where grid reliability is limited. The wide operating temperature range and high cycle life make this the preferred deep cycle lithium battery choice for off-grid EPCs and project developers.
Deye Inverter Compatible — Plug-and-Play Integration
Pre-validated with Deye hybrid inverters via CAN BMS protocol — no manual parameter configuration required on-site.
Deye SUN Series (5kW–80kW)
Fully tested and documented for plug-and-play integration with Deye SUN-29.9K~50KSG01HP3 and SUN-80K-SG02HP3-EU-EM6 inverters. Connect via CAN to the inverter BMS port; the battery main module auto-negotiates SOC, charge limits, and protection thresholds. For single-module installs on Deye 29.9K–50K inverters, use the dual-port parallel shunt configuration (P1+/P1– → BAT1; P2+/P2– → BAT2) to maximize power delivery.
Broad Third-Party Inverter Compatibility
Beyond Deye, the CAN/RS485/RS232 multi-protocol BMS supports integration with most leading hybrid inverter brands. Contact our technical team for a validated compatibility list covering SolarEdge, Growatt, Sungrow, Victron Energy, Fronius, and GoodWe.

Frequently Asked Questions About Our 200Ah Lithium Battery
What is the usable energy of this 200Ah lithium battery at 90% DOD?
At the recommended 90% depth of discharge, the 51.2V 200Ah unit delivers 9,216Wh (9.22kWh) of usable energy per cycle. This is the figure to use when sizing residential solar-plus-storage systems, not the nominal 10.24kWh total capacity.
How many units can I connect in parallel?
Up to 15 units can be connected in parallel, scaling total system energy to a maximum of 153.6kWh from a single battery string. All units communicate through a shared CAN/RS485 bus managed by the master BMS module.
Is this battery compatible with Deye inverters out of the box?
Yes. The 51.2V 200Ah-LV has been tested and documented with Deye SUN series hybrid inverters (5kW–80kW range). Communication is established via CAN bus connected to the inverter's BMS port. Detailed wiring diagrams and inverter parameter settings are included in the installation guide.
What certifications does this battery hold?
The 51.2V 200Ah-LV holds CE, RoHS, IEC62619, MSDS, and UN38.3 certifications. The IEC62619 certificate covers both cell-level and system-level safety testing, making it compliant for residential installation in the EU, UK, Australia, and most international markets.
Can I order with my own brand name and packaging?
Yes. We offer full OEM private label services including custom branding, enclosure colors, BMS display graphics, and multilingual documentation. Minimum order quantities start at 20 units. Contact our OEM team to request a sample and discuss your project timeline.
