A buyer running a small solar farm recently needed a battery system that could sit outside in rain without extra enclosures, and that's where this IP65-rated rack comes in — they just mounted it on a concrete pad and wired it up, no shelter required.
We've tested these modules at 0.5C charge and discharge through 4000 cycles at 80% depth of discharge, and they still hold above 80% capacity, which is better than most LFP packs we've seen at this price point; the system votage range sits between 313.6V and 681.6V depending on how you stack the modules (usually 7 to 15 units in a rack).
Natural convection cooling means no fans to fail, but don't push it past 0.5C continuous — it's not suited for high-rate pulse applicaion like some NMC chemistries, though for telecom backup or off-grid storage it basically runs itself.
The 280Ah modules weigh about 30kg each or so, and the rack dimensions vary form 900×950×1100mm to 1850mm tall depending on your configuration.
Each module ships with a CE and UN38.3 certifcate, and we'll retest any batch that doesn't match the original COA — just send back the samples within 30 days.
MOQ is 4 racks, lead time is roughly 6-8 weeks, and we usually have stock for the 14.336kWh modules but confirm before ordering.
No, all modules in a rack must be the same 280Ah capacity to keep the voltage and BMS communication consistent. Mixing different Ah ratings would cause imbalance and could damage the system.
Our MOQ is 10 units per order for standard configurations, but we can discuss smaller quantities for first-time buyers or sample testing. Just reach out to our sales team.
Lead time is typically 20-25 working days after order confirmation. Yes, CE and UN38.3 test reports are included with every shipment for customs clearance and compliance.
IP65 means the battery is fully dust-tight and protected against low-pressure water jets from any direction, so it can be installed outdoors in shaded areas without extra enclosures. Just avoid direct submersion or high-pressure washing.
Both RS485 and CAN are available, and we can set the default protocol to your preference before shipping. Just let us know which one you need, and we'll configure it at the factory.
