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. All-in-one inverters combine a solar inverter, charger and battery inverter together with software which can be programmed to determine the most efficient use of your available energy.

Having all the components in one simple plug and play unit means hybrid inverters are generally much lower cost and easier to install but they do have several limitations, in particular lower surge power output (as they are typically transformerless) and low backup power - see below.

Backup Power

Most all-in-one inverters have very limited pass through power capability so require separation of essential and non-essential loads. Essential loads are basic loads (circuits) which can be easily 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 generally require a more powerful multi-mode interactive inverter system. However all-in-one hybrid inverters can be very good choice for those who just want to be more self-sufficient using batteries and don't intend on disconnecting from the grid or rarely experience blackouts.

Battery Compatibility

Most leading all-in-one hybrid inverters are designed to be used with modern lithium battery systems as opposed to conventional lead-acid battery banks. In addition there are now two main lithium types available, the more common extra low voltage (48V) systems and now higher voltage (300-500V) systems are available.

Most lithium batteries contain a battery management or control system (BMS) and due to the specific requirements of each battery type the BMS must be compatible with the inverter or it will not be able to function correctly and could lead to overcharging and overheating the battery.

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. The popular (ebay) Voltronic inverters (MPP solar and Infini hybrid) are a very economical all-in-one system but have been reported to have some quality and reliability issues and are not compatible with the new generation lithium battery systems from LG chem, BYD, PylonTech etc.
