Chinese inverter maker Growatt has unveiled the SPF 3000T HVM-G2 inverter for off-grid solar power systems.
The device consists of a built-in MPPT charge controller, an AC charger, and an inverter with a low-frequency transformer. “It allows for surge power at three times of the rated power to support motor-type loads or inductive loads,” the manufacturer said in a statement. “Additionally, thanks to its optimized product design and improvements in both software and hardware, the inverter has a longer design life and comes with a five-year product warranty as standard.”
The 3 kW inverter has an efficiency of 95%, a surge power of 9000 VA, and solar input voltage up to 250 V. It can be connected in series for up to six units for single-phase or three-phase systems to expand capacity to 18 kW.
The device, which also features IP20 enclosures, measures 225 x 300 x 550 mm and weighs in at 27 kg. Its operating ambient temperature ranges from -20 to 50 degrees Celsius.
Growatt stated that the inverter enables power input from multiple sources, including any power generator, a solar array, a storage system, and the power network. “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 that are well-known for [their] safety and reliability,” it further explained. “Additionally, it is designed with Low Voltage Disconnect protection function for batteries.”

Can you pls share comparison of Lithium Ion and Iron Phosphate batteries.
Just started getting articles in my feed today. This is the third one, and I have linked to two others from those. Really enjoy your style, in how the technical details are presented. And with enough depth, that i don’t have to find, then slog through a ‘whitepaper’ spec sheet to get more than just the cursories from a cut sheet.
But, I criticize the lack of MSRPs. I understand different pricing for different scales, and such. At least a probable range would be nice. Sort of negates not having to hunt for specs, but for pricing.
Not so much a criticism, just an fyi, is that when I hyperlinked toward the companies,to find pricing, they seemed to redirect to bogus looking pages that triggered a security risk alert. Higher threat level than a ” no valid cert” or ” not secure, enter/leave?” Those usually get ingored. These got browser restarts. Tried again, same scenario, but page names changed. From this article and the one about the 580-620W panel just out.
