Australia is expected to be the world’s largest residential energy storage market in 2019 according to Bloomberg New Energy Finance, accounting for 30% of global demand as household storage demand triples. An increasing amount of Australian households are now installing or at least investigating solar energy storage systems.
Whilst lithium prices are slightly decreasing however still considered relatively expensive, therefore more consumers are looking for a ‘battery ready’ solar solution, allowing for the addition of battery storage at a later date. GoodWe has recently launched its brand-new EHR Series battery-ready inverters with power classes 3.6kW, 5kW and 6kW. Nothing more than an activation code is required to upgrade from a grid-tied inverter into a hybrid inverter.
The EHR series is a truly battery-ready solar solution. When the time comes to add batteries, the batteries are simply connected directly into your existing inverter without any additional equipment and only an activation code is required. Batteries can actually be added onto any existing solar system as long as they have their own connection to the AC mains grid. GoodWe also provides their own AC-coupled retrofit solution called “SBP Series” which can be used for any new or exisiting solar installation.
The EHR series, as a battery-ready product has it’s unique advantages in the application of both on-grid solar systems and energy storage systems. The EHR series can be used as a single-phase gird-tied inverter with compatibility to bifacial double-glass modules, allowing 12.5A input current per string. EHR has 33% DC oversizing capability to fully maximize capacity and a wide MPPT voltaje range. Furthermore, EHR is a perfect match for eco-friendly residential installations thanks to their die-casting aluminium casing, compact size and light weight.
Once the EHR Series is activated by the GoodWe code, it then becomes a complete hybrid inverter compatible with high voltage batteries. EHR can be connected to a wide range of lithium-ion batteries ranging from 85V to 450V, with an overloading capacity of 20%. The power deviation from inverter’s AC output to load consumption can be as low as 20W, maximizing solar energy consumption.
Given that it takes less than 10s to switch from grid power supply to PV supply when heavy loads startup, this in turn minimizes the consumers expensive power intake from the grid. It alsocomes with an automatic UPS function that is activated within 10ms. When in back-up mode the EHR series can still supply power to large loads such as heating and cooling given the large backup and overload capability. EHR Series is equipped with pre-wired communication cables and plug & play AC connectors, which minimizes the installation time and maxizes strong profitability.
As solar photovoltaic and energy storage prices continue to fall, electricity prices continue to rise therefore customers want greater control over their electricity usage and are seeking ways in which they can reduce their power bills. GoodWe’s EHR series battery-ready inverter is the perfect flexible option in order to make it easier when the time comes to add batteries in the following years to come.
