product description：
Off-grid inverter adopts industrial design standard, with high stability, reliability and efficiency. The off-grid inverter is designed by STM32. The core controller has 64K Flash, 20K SRAM and 72MHz main frequency. The high-performance controller can verify various control algorithms. The off-grid inverter adopts imported NMOSFET with high power and low internal resistance as the power device, and H bridge is driven by IR2110S driving power component. The core control module adopts modular design, which can be used to drive SPWM signal of h-bridge with high voltage side of various inverters. Inverter features: DC input DC12V, inverter output AC220V, the maximum power of 300W, with DC input reverse connection protection, DC input overvoltage/undervoltage protection, AC output overcurrent protection.
