The SPF 3500 ES is suitable for smaller loads and a single roof area. The SPF 6000 ES Plus has two module inputs and can handle almost double the module power. Both units are protected to IP20 and should be installed in a dry indoor location, not on an external wall. The data sheet for each unit specifies which batteries the manufacturer approves for use.

For systems with a grid connection and storage, hybrid inverters are the appropriate type. Batteries are listed under Energy Storage, whilst a comparison of all types can be found under Inverters.
