When you've got a bank of industrial UPS systems or solar storage racks that need consistent 48V bus voltage without sagging under heavy loads, what it does is switch from lead-acid to LFP and suddenly your discharge curve stays flat at 51.2V until it's basically empty — that's the whole point of the RackArk-10240, it gives you a solid 200Ah at nominal with the votage stability that makes BMS integration way simpler.
Cycle life is 6000 cycles at 80% DOD, so figure 15 years or so for most daily cycling application, and the 10 years which is pretty much teh longest we offer — charge temp range is 0°C to 65°C, but discharge goes down to -20°C, so it'll run in cold storage facilities or outdoor telecom cabinets without drama, though charging below freezing needs the built-in BMS to handle it.
Max discharge current is 100A continuous, and you can push 80A charging without any thermal issues we've seen — the discharge cut-off is adjustable from 40V upward (usually we set it at 40V for most customers) but some guys running high-discharge pulse loads prefer 42V for extra safety margin, just tell us your preference and we'll configure it before shipping.
82kg per unit, cabinet-style insallation, and you can parallel up to 15 units for a 3000Ah system — the LCD display is optional, most buyers skip it and just use RS485 or CAN bus for monitoring, but if you need local readout it's an extra 40 bucks or so.
One thing that catches people off guard is the standerd charge voltage of 58.4V is adjustable but the BMS firmware locks it at that number out of the box — if your inverter expects 56V absorption you'll need to request the custom setting before we ship, because we can't change it remotely after delivery.
MSDS, UN38.3, and IEC62619 certs are on file, we send a fresh COA with each batch — lead time is usually 20 working days for a single unit, but if you order 10 or more our company can shave that to 14 days (check current production schedule though, because sometimes LFP cells get tight).
We typically require a minimum order of 10 units for the RackArk-10240, but we can discuss smaller quantities for initial trials or specific projects.
Standard lead time is around 15-20 working days after order confirmation, though it can vary slightly depending on current production load. We'll give you a firm ETA when you place the order.
Yes, we can provide the CE and IEC62619 test reports and certificates for the RackArk-10240. Just request them from your sales contact, and we'll send the docs over.
You can connect up to 15 units in parallel. The built-in BMS handles communication between them, so no extra controllers are needed—just standard cabling and the CAN or RS485 interface.
Yes, both the standard charge voltage (58.4V) and discharge cut-off voltage (40V) are adjustable through the BMS settings. You can tweak them via the RS232 or CAN interface to match your system requirements.
