So you've been looking at home storage options and you're probably tired of dealing with systems that just don't hold up over time — we've been moving these for about four years now and the main thing buyers come back to us about is the testing we put each unit through before it ships.
You're looking at 48V nominal with a 100Ah capacity giving you that 5KWh, and the thing that actually matters for your setup is the operating voltage range form 42 to 55V because that determines how well it plays with your inverter, plus the cycle life is rated at 6000 cycles or so but we usually see them going well past that in real-world use.
Every single pack gets a full charge-discharge cycle at teh factory with the data logged and attached to the serial number, and we also run a four-point internal resistance check across the cell groups — it's basically what separates our stock from the random stuff you see on marketplace sites where they just slap a label on it.
BMS is set up with CAN and RS485 communication ports as standard, but we can customize the protocol if you need it for a specific brand of inverter — just give us a heads-up before ordering and we'll flash the firmware, though I should mention we usually have stock of the standerd version ready to go within 10 working days or so.
You'll get the CE, Un38.3, and MSDS certs with each shipment, and we back it with a 5-year warranty that covers manufacturing defects — if you run an independent HPLC test and it doesn't match the COA we provided, we'll replace the whole unit, no questions asked, and we've only had that happen twice in the last 300 units we've moved.
Our standard MOQ is 10 units for the GBP48-100R, but we can negotiate smaller trial orders for first-time buyers. Just reach out to our sales team to discuss.
Custom orders typically take 15-20 working days from order confirmation, depending on volume and port configuration. We'll give you a precise timeline after you specify your requirements.
Yes, all units are certified with CE, Un38.3, and MSDS. We can provide copies of these documents upon request to support your shipping or installation compliance.
It can operate at -30°C, but performance may dip. For best results, we recommend keeping it between 10°C and 35°C. Charging below 0°C requires a low-temperature cutoff feature, which we can include in customization.
Each pack is shipped in a reinforced wooden crate to prevent damage during transit. For storage, keep it in a dry place with humidity between 0-95% RH—ideally below 85% RH for long-term storage to maintain battery health.
