That does not<\/strong> automatically mean buying a battery labelled \u201c5kWh.\u201d<\/p>\n

Nominal capacity is the headline figure. Usable capacity reflects the manufacturer\u2019s operating limits. Inverter losses and any backup reserve further affect what reaches your appliances. Don\u2019t deduct the same discharge allowance twice if it is already included in usable capacity.<\/p>\n

Check different seasons, too. A sunny July afternoon won\u2019t tell you much about a cloudy winter week.<\/p>\n

4. Will It Run the Appliances You Care About?<\/h2>\n

Capacity and power are different things.<\/p>\n

kWh tells you how much energy is stored. kW tells you how quickly the system can supply it.<\/strong><\/p>\n

A battery might hold enough energy for an evening but still be unable to run the oven, kettle and other large appliances together.<\/p>\n

Give your installer a list of what you want to run. Ask about continuous output and the extra power some appliances need when starting.<\/p>\n

5. What Does a Solar Battery Retrofit Cost Include?<\/h2>\n

The battery price is only part of the bill. Ask for an itemised quotation covering:<\/p>\n
