I was using a 12v, 1000w inverter and was underwhelmed. This VEVOR 24v, 2500w is working fine. The displays are not very accurate but the performance is great. I charged my Golf Cart with 6 8v Trojan 170AH batteries and ran a 6.5 cubic foot freezer at the same time without a hitch. I have 2 100AH LifePO4 batteries in series powering this inverter. I am satisfied with this inverter. The output voltage and frequency on this inverter are accurate but I use the epever T50 display for the battery voltage.
