Batteries let you store and timeshift power. They can store solar-generated power or cheap, off-peak power. To make this work, you need a TOU tariff with a decent peak/off-peak rate spread. Last week, I traveled to London to see some new products EcoFlow is releasing now that plug-in solar is set to become legal here in the UK. But what struck me was how I feel that pure plug-in solar has already been superseded by hybrid systems offering greater potential for savings. Don't get me wrong, I still think there's a place for pure plug-in solar systems where you take solar panels, hook them up to a microinverter, and feed that power into your system to handle…
