They have a good track record with their inverters and are our preferred Chinese brand of inverters as they are a solid performer which we have found to be very reliable. If cost is a concern for you when installing a solar PV system then this is a brand that will serve you well. There Crystal Premium single-phase inverter that was redesigned recently to include a DC isolator which removes the need for additional DC isolators to be installed next to the inverter, they have also kept the screen on the inverter when many others are removing theirs. Their Crystal Premium single phase inverter range also does go right up to the Premium 8kW inverter which is great for those of you who require that little bit extra on your roof to handle those hot summer days. The 8kW unit was a welcome addition not so long ago and has been a unit that has fitted into the market just perfectly.
