If, on the other hand, you want to evaluate a battery purely on its own merits (as most people will – especially if they’re considering retrofit for an existing solar system), use method B – it is a much stricter way of evaluating a battery’s investment-worthiness. That being said, if you’re looking only at the value directly associated with the batteries (‘battery only’ evaluation method), it’s highly unlikely that you’d bother with them. In comparison to other solar batteries in Australia, Enphase offers one of the cheapest products on the market. The point being that there is definitely an advantage to having a battery with higher instantaneous power output, but in homes with only moderate levels of energy consumption (say 15-25kWh per day and at least 5kW of solar), it probably won’t make a huge difference. Plus, flexible configurations work for any garage. Your actual savings will depend on your own circumstances, including how much you pay for electricity, how you use electricity throughout the day and whether you’re on a flat rate tariff or time of use tariff (<– If you don’t know what this means, or which tariff type you’re on, definitely read this article.).
