I'm reaching out to get a quote for two lithium batteries designed for solar systems, ideally in the 15 to 16 kWh range. We're looking for reliable performance and longevity, as these will be a key part of our renewable energy setup. Could you please provide details on pricing, availability, and any specifications that might be important? Additionally, it'd be great to know about any warranties or support services you offer with these batteries. Thanks!
