3. All-in-one hybrid inverters

Jason Svarc

hybrid solar inverter review comparison

The most economical type of hybrid system uses an all-in-one hybrid inverter. The all-in-one inverters contain a solar inverter, charger and battery inverter together with software which can be programmed to determine the most efficient use of your available energy.

All-in-one hybrid inverters are lower cost and easier to install but they do have some limitations, in particular lower surge power output. Also most all-in-one units have very limited pass through power capability so will require separation of essential and non-essential loads. Essential loads are basic loads (circuits) which can be backed up in the event of a blackout, such as lights, low power appliances, TV's and computers. To back-up an entire house you would generally need a more powerful interactive inverter system.

It is worth noting that if using an all-in-one hybrid inverter with a lead-acid Gel or AGM batteries only the Redback and Sungrow inverters have temperature monitoring to optimise battery charging. PowerRouter from Nedap has been recalled in Australia and the Voltronic inverters (MPP solar and Infini hybrid) have been reported to have some quality and reliability issues.
