3. All-in-one hybrid inverters

Jason Svarc

All-in-one solar hybrid inverters 2018.png

The most simple and economical solar and battery systems use an all-in-one hybrid inverters. 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) with limited backup power capability - see details below.

Backup Power

Most all-in-one inverters have limited surge power output and no pass through power capability so separation of essential and non-essential loads is required. Essential loads are basic loads (circuits) which can be easily backed up in the event of a blackout, such as lights, fridge's, TV's and computers. To back-up an entire house you generally require a more powerful AC-coupled interactive inverter system.

All-in-one hybrid inverters are a very affordable choice for average size households who want to be more self-sufficient using solar and batteries but 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 like LG chem as opposed to conventional lead-acid battery banks. There are now two main lithium types available, the common extra low voltage (48V) systems and now higher voltage (300-500V) battery systems are available.

Modern lithium batteries contain a BMS (battery management system) which manages the charge/discharge, cell voltage and temperature. Due to specific charging requirements of different lithium battery types the inverter must be compatible with the BMS 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 lead-acid (Gel, AGM or lead-carbon) batteries very few inverters have temperature monitoring to optimise battery charging (refer to spec sheets). The cheap Voltronic inverters (MPP solar and Infini hybrid) are an economical but have been reported to have several quality and reliability issues and are not compatible with the new generation lithium battery systems from LG chem, BYD, & PylonTech.
