On small islands or in developing and rural areas where there’s limited or even no access to the grid, off-grid solar power has become an increasingly popular energy solution. However, there’re many technical challenges holding back the market. Aiming to simplify things, Growatt debuted the second generation of its off-grid inverter, SPF 3000T HVM-G2, which can be combined with Growatt’s wide range of lithium batteries and monitoring solutions.

The SPF 3000T HVM-G2 inverter consists of built-in MPPT charge controller, AC charger and inverter with low frequency transformer, allowing for surge power at three times of the rated power to support motor-type loads or inductive loads. The SPF 3000T HVM-G2 inverter also enables power input from multiple sources such as generator, solar, storage battery and the grid. The owner can use electrical power from the grid and PV system together to power household loads. The inverter comes with a five-year product warranty as standard.

The inverter can work with or without batteries, and it is compatible with mainstream lead-acid and lithium-ion batteries including Growatt’s Lithium Iron Phosphate (LFP) batteries. Additionally, it is designed with low-voltage disconnect protection function for batteries. When battery voltage drops down, it will first disconnect non-critical loads from the system in order to extend backup time for critical loads.

The SPF 3000T HVM-G2 inverter has efficiency up to 95% and a low energy loss with only 9W power consumption at power saving mode. The inverter also has the bypass function that allows the user to by-pass the normal functioning of the inverter and use power from the grid. With high solar input voltage up to 250V, it makes installation much easier and reduces BoS costs as well. The inverter can be connected in parallel for up to six units for single-phase or three-phase systems to expand power capacity to 18-kW.

Have you checked out our YouTube page?

We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.

Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We discuss everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
