澳大利亚采购需求：大功率逆变器，修正正弦波逆变器，带充电器的修正正弦波，电源逆变器

I'm looking for pricing details on a 2000W home car power supply that includes a battery charger. Could you provide the cost along with any bulk order discounts if available? Additionally, I would appreciate it if you could share information regarding the specifications, lead time for delivery, and payment terms. This will help me make an informed decision. Thank you!
