Technical parameter：
Three-phase industrial frequency inverter is a device that converts direct current (DC) into three-phase alternating current (AC), with the output frequency typically being the industrial frequency, which is 50Hz or 60Hz in most countries. One important aspect to note is three-phase modulation: for a three-phase inverter, it is necessary to generate three sine waves that are 120° out of phase with each other. By controlling different switch combinations, three-phase output can be achieved.
This model is a pure energy storage inverter that only accepts DC48V battery input and does not integrate MPPT. If photovoltaic function is required, it is recommended to pair it with a separate photovoltaic charging controller or choose a hybrid inverter (such as PW series).
Power frequency "refers to the internal use of power frequency isolation transformers, which, although slightly larger in size and slightly less efficient than high-frequency models (typical efficiency of about 90-92%), have extremely strong surge resistance, electrical isolation, and long-term reliability, making them suitable for supplying power to critical loads.
DC48V belongs to the Safety Extra Low Voltage (SELV) category, which significantly reduces the risk of electric shock. It is particularly suitable for off grid or microgrid scenarios that require high personal safety, such as homes, schools, and islands. It is also compatible with common 48V lead-acid/lithium battery systems.

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
