I'm interested in sourcing a hybrid inverter with a capacity of 20kVA, along with a suitable lithium-ion battery. The inverter should be efficient and reliable, designed for both solar and grid use. Additionally, I'm looking for high-quality solar panels; specifically, I'd prefer options with a power rating of around 620W. Moreover, I need aluminum frames to support the installation of these solar panels. It's essential that all components are durable and compatible with each other to ensure a seamless integration into my energy system. Kindly provide me with detailed product specs, pricing, lead times, and any available warranties for these items.
