For home use, the Tesla Powerwall is popular. https://www.tesla.com/powerwall https://www.tesla.com/powerwall. It gets expensive if you want to ride out several cloudy days in a row.
It's inefficient to have off-grid battery systems for every home. If you can average supply and demand across an entire grid, you need much less storage per person. And you can use storage systems with higher fixed cost but lower cost per kWh, like pumped hydroelectric.

Wind can compensate partially but you still need a 100% solution and don't want to give up your country energy security and depend hard on others because if bad weather happens then they will not send you energy and keep it for thir own population.
