This is the Rolls Royce of inverters. It is perfect for my caravan when at sites with no hook up. It has plenty of power and runs a microwave with ease. It has a built in charger to charge the battery when at sites with hook up. The control panel lets you change settings to suit your needs. I changed charging output from default 75A to 10A and output voltage from default 230V to 240V. The unit doesn't come with cables to connect to battery or mains cable or output cable to connect to appliances but these are easily purchased although I had to modify them slightly to connect to the unit as it has a block connector for 240V input and output. The fan cuts in when under load and when charging the battery and is quite loud so be aware of this.In summary it is good value for money considering what you pay for basic pure sine inverters. It is quite large and heavy but will fit under a caravan seat and has many features and settings. I would highly recommend it.
