The LG Chem is a Residential Energy Storage Unit (RESU) featuring a 48V (nominal 51.8V) lithium ion battery with integrated battery management system.
The battery is designed to tie in with a grid connect solar system to increase self-consumption and savings. An additional inverter (e.g. SMA Sunny Island) is also required. Of course, the battery pack can also be utilised in an off-grid situation.
The LG Chem has a life expectancy of over 10 years (and a ten year warranty to prove the point). It can be cycled (discharged and re-charged) 6000 times to 90% Depth of Discharge (DoD), meaning only 10% left in the battery. In $/kWh, this is possibly the cheapest battery on the current battery market.
Phonocube is an energy management unit that is suitable for integration in both new and existing photovoltaic systems. It combines the inverter, batteries and the photovoltaic system into one compact system.
Controlled by a SMART ENERGY MANAGEMENT SYSTEM (SEMS), Phonocube makes it possible for photovoltaic system owners to use PV electricity for their own requirements not only during sunlight hours but also at times of less light; such as in the morning or evening. Electricity produced by the photovoltaic system can be consumed directly, stored in the batteries or fed into the public grid. Phonocube ensures self-consumption is prioritised; grid power will only be used when neither the photovoltaic system nor the batteries are able to supply sufficient electricity.
Phonocube presents you not only with an essential product, but with an energy management solution. You will notice nothing different, except the reduction in your electricity bills!
