In 2018, PowMr launched its first self-branded product — the HHJ-60A solar charge controller. Designed for 12V/24V/36V/48V systems with a robust 60A charging capacity, it offered exceptional performance at a highly competitive price. The HHJ-60A quickly became a global bestseller and remains influential today, with many similar products on the market inspired by its success.

In 2021, PowMr introduced the POW-Keeper (25A/35A/45A) and POW-M60 charge controllers for small to mid-sized off-grid systems and expanded its lineup with pure inverters (POW-LV, POW-HV) and all-in-one inverters (POW-HVM5.5K, POW-HVM-H, POW-LVM), covering 1.2kW–5kW output, 12V–48V systems, and 110V/220V AC. This upgrade completed PowMr’s small power off-grid portfolio with flexible options for both 110V and 220V markets.

In 2022, PowMr upgraded the POW-HVM-H and POW-LVM series for easier operation and improved output. The new POW-HVM-M series (4.2kW/6.2kW/10.2kW) launched with dual MPPT, independent WiFi and BMS ports for high-power off-grid systems. The POW-LVM series was upgraded to high PV input, allowing more solar input. PowMr also introduced the POW-SunSmart 5kW/10kW series for large off-grid setups, and officially entered the energy storage market with the POW-LIO48100-15S and POW-LIO48200-15S.

In 2023, PowMr upgraded the HHJ-60 to HHJ-60Pro with parallel support, launched POW-M series controllers with 80A/100A to meet higher user demands, and enhanced the POW-M60 to M60-MAX with a larger screen and built-in terminals for easier use. The POW-SunSmart 8/10/12kW series debuted for three-phase off-grid systems, alongside the POW-LIO51300-16S wheeled battery series, further expanding the energy storage lineup.

In 2024, PowMr introduced parallel functionality to multiple products, including the POW-M60-ULTRA and POW-SunSmart 8/10/12kW series. The Keeper series was replaced by the upgraded POW-M series (25A/35A/45A). In energy storage, PowMr enhanced its lithium battery design by upgrading from 15 to 16 cells, significantly improving overall performance.
