Factory Supply 48V 150AH 200AH Wall Mounted Solar Lithium Battery with NCM Cathode

Actually looked over your inquiry and we've been shiping these wall-mounted units for a while now—the 200AH version is roughly 45kg and pretty manageable for one person to lift onto a bracket, though you'll want a helper for the initial alignment since teh mounting plate has to be level within about 2 degrees or so.

We've got three capacity options: 100AH, 150AH, and the 200AH that most buyers go with for residential solar storage, and they all run at 48V or 51.2V nominal depending on the BMS configuration you choose. The NCM cathode gives you better energy density than standerd LFP, which is why the 200AH unit fits into a 442x420x133mm footprint—about the size of a small suitcase. But here's a thing a lot of people don't think to ask: the peak discharge of 150A only holds for 5 seconds, so if you're planning to run heavy loads like a well pump startup surge, you'll want to calculate that carefully (usually 2-4 weeks lead time on custom BMS settings for that). Charge temperture is 0°C to +45°C, so it's not suited for freezing garages unless you keep it above freezing during charging.

Cycle life is ≥3000 cycles at 80% depth of discharge, which is better than reagent grade for this appliction but still means you'll see gradual capacity fade after about 8 years of daily cycling if you're running them hard. We back them with a warranty that's 3, 5, or 8 years depending on the tier you pick—the 8-year option basically covers the full expected lifespan at moderate discharge rates.

RS485 and CAN communication interfaces are optional but pretty much standard for anyone integrating with a modern inverter—we usually stock the RS485 version and can swap to CAN if you give us a heads up. It's got CE, RoHS, ISO9001, and UN38.3 certifications, though the IP20 rating means it's strictly indoor use or in a weatherproof enclosure.

Anyway, for ordering we typically run MOQs of 10 units on the 200AH, but our company can do smaller test batches if you're evaluating the form factor for a specific project—just confirm lead time because the NCM cells have been fluctuating in availability lately. The efficiency rating is ≥95%, so what that means in practice is you'll lose about 5% of your solar input as heat during charge-discharge cycles, which is tighter tolerance than most wall-mount units in this price bracket.
