We've got teh GzS series sitting in our bonded warehouse right now, so stock isn't issue — shippng via sea freight takes about 18-22 days, and we can do air if you're in a real hurry, but the lead time for that is usually 7-10 days depending on customs.
Basically, these are for when you need a battery that won't quit after a few deep cycles — the tubular positive plate design handles the kind of daily discharge you'd see in off-grid solar, and the Pb-Ca-Sn-Ag alloy on that plate is what gives it the 20-year float life, though honestly most buyers don't push it that far.
It's not great for high-rate discharge application like UPS backup where you need instant surge — the 2V flooded design is better suited for slow, steady draw over hours, and the capacty range goes from 200AH up to 3000AH at the 10HR rate, so you can size it for a telecom station or a small power plant.
The operating temp range is pretty wide at -45°C to 60°C, which matters if you're installing in a desert or a cold climate, and the micro-porous PVC-SiO2 separator is what keeps the electrolyte from stratifying during those long float periods.
Each unit comes with copper terminals that have a corrosion coating — that's a detail a lot of buyers don't think about until they see the green crust after a year, and we always include the COA with HPLC data on the electrolyte purity, which is usually tighter than reagent grade for this application.
Packaging is standard wooden crates with foam inserts, about 50 units per pallet for the 200AH size, and we can do partial shipments if you're testing the waters with a small order first.
We typically require a minimum order of 20 units for the GzS series, but we can be flexible for large-scale solar projects. Contact us to discuss your specific needs.
Lead time is usually 30-45 days from order confirmation, depending on the capacity and quantity. For a 2000AH model, we can ship within 35 days if stock is available.
Yes, the GzS series is certified under ISO9001, ISO14001, CE, and RoHS, so they meet international quality and safety standards for renewable energy applications.
Sure, the 3000AH model delivers 3000 amp-hours at the 10-hour discharge rate. That's the standard capacity spec for our GzS series in solar setups.
Store them in a cool, dry place at 15-25°C, keeping the terminals clean and the electrolyte level topped up. They can sit for up to 6 months before needing a recharge.
