The Powerwall 2 is a great product, its attractive for a battery, has a decent amount of storage and a well designed app. Being an AC coupled battery though, it has its pros and cons.
What’s an AC Coupled Battery? – Put simply, it means that the battery charges itself from AC power. It senses surplus solar power and absorbs it and then allows the surplus energy to be exported once the battery is full.
The up side of this is that it can be installed with any solar system. It doesn’t “talk” to your solar system at all so it doesn’t care what solar system you have.
On the down side, it has a 5kW inverter built-in which in Queensland counts towards your total inverter capacity allowance with Ergon and Energex. In Queensland, there is a limit of 10kW of Inverter capacity for single phase properties and because the Powerwall is 5kW, you will then be limited to a 5kW Solar inverter.
The Adaptable Solar Storage Solution The Huawei LUNA energy storage system is here. The perfect option to couple with any Huawei Hybrid inverter, the LUNA can be modified to suit your energy needs, however large they may be. Thanks to its modular design, rather than having to buy an additional battery if you want to expand your home’s energy storage reserves, all you need to do is add another battery block to your LUNA, saving you money and space. Due to this clever design, the LUNA can scale in size anywhere from 5 kWh all the way to 30 kWh.
BYD’s solar energy storage system, the Battery Box Premium comes in two types, the HVS and the HVM, between the pair, they are able to offer a variety of energy capacities, thanks to the battery boxes modular design.
