Peak Load Shifting LiFePO4 Energy Storage System 51.2V 200Ah Modular Cabinet Smart BMS
Peak Load Shifting LiFePO4 Energy Storage System 51.2V 200Ah
EC-PS1024 — The Bill-Cutter for Commercial Electricity Users
If your electricity bill has a line called "demand charge" or you pay different rates at different hours, this cabinet pays for itself. The EC-PS1024 is a modular 10.24kWh LiFePO4 storage block that shifts your consumption from expensive peak hours to cheap off-peak hours - automatically, every single day.
Here is the math in plain language: you charge at night when energy costs a fraction of the day rate, and discharge during the day when the grid rate is highest. The difference between those two rates is your saving, multiplied by every kWh the system moves.
The Saving Mechanism
The built-in EMS reads your tariff schedule (up to eight daily periods) and your real-time load. It then runs a simple optimization: buy low, sell high, never let the load spike past your demand threshold. When the grid fails, the same unit switches to backup mode and keeps your lights, servers or refrigeration running.

Growing With You
Start with one module and add more as your load grows. Modules stack with locking brackets and connect through a single communication bus - no re-wiring of existing modules. Ten modules form a 102.4kWh string that handles most small factories and retail sites.
What Is Included
Each order includes the battery module with integrated BMS, stacking brackets, communication cables, the EMS gateway with WiFi, a one-year cloud monitoring subscription, and the installation manual. A compatible hybrid inverter can be supplied on request.
Frequently Asked Questions
Will it work with my existing inverter? It communicates over CAN/RS485 with most hybrid inverters; send us the model and we will confirm compatibility. Is it noisy? No fans, no moving parts - it is silent. Can it run three-phase loads? Yes, when paired with a three-phase hybrid inverter. What if tariffs change? Update the schedule in the APP in under a minute. Do you install it? We provide remote guidance; local installation partners are available in most regions.
BMS Protection Table
| Protection Function | Setting / Behavior |
|---|---|
| Cell over-voltage | 3.65 V per cell, disconnect and alarm |
| Cell under-voltage | 2.50 V per cell, disconnect and alarm |
| Over-temperature | 60 deg C charge / 65 deg C discharge cut-off |
| Low-temperature charge | Blocked below 0 deg C |
| Short circuit | < 1 ms trip, auto-recovery after fault clear |
| Cell balancing | Active, triggered during charge at 3.40 V |
Installation Notes
Modules arrive on a pallet and are placed on a level indoor floor. Stacking brackets click together without tools; the communication cable daisy-chains through the modules and connects to the EMS gateway. The gateway then talks to your inverter or meter over CAN/RS485. Clearances of 300 mm on top and 500 mm in front are sufficient for service access. Full installation typically takes two technicians half a day for a three-module system.
More Questions
What if my business grows beyond 102.4 kWh? Multiple strings can be paralleled with additional gateways. Does it work with generators? Yes, the EMS can prioritize generator or battery based on fuel cost. Can I see historical data? The cloud portal stores five years of history with export to CSV. What is the response time in backup mode? Transfer happens within 10 ms. Do you offer leasing? In select markets we offer energy-as-a-service; contact us to check availability.
