Inverters

Every Deye hybrid inverter needs to measure what is flowing in and out at your grid connection, so it can keep to your export limit and use your solar and battery sensibly. There are three ways to do that. The standard way is the current clamps supplied with the inverter, which run on a lead back to the inverter and suit most homes. If your switchboard is a long way from the inverter (Deye suggests around 10 metres or more on the three phase units), the usual answer has been a wired energy meter in the switchboard connected to the inverter by a data cable. The wireless Smart CT is the third option: it is a small meter that sits in your switchboard, powers itself from the supply it measures, and sends its readings to the inverter by a short range radio link (LoRa) instead of a cable. It works on single phase and three phase supplies. It needs one small companion part on the inverter, the Deye Smart Transmitter, which is the receiver for that radio link. The same transmitter is what lets a Deye EV charger and Deye smart switches talk to the inverter, so if you are planning a Deye EV charger with solar only charging, the wireless Smart CT is the natural choice for grid measurement because both use the one transmitter. We sell the wireless Smart CT as an option on our Deye inverter listings.

Yes. The wireless Smart CT sends its readings by radio, and the Smart Transmitter is the receiver that plugs into the inverter. Without it the inverter cannot hear the Smart CT, the Deye EV charger, or any Deye smart switch or plug. One transmitter serves all of them: Deye rates it for two Smart CTs, one EV charger and up to ten smart switches or plugs at once. Our wireless Smart CT option includes the transmitter. Make sure any Deye radio device bought for Australia is the Australian version (the model numbers end in U1), because the European version uses a different radio band and will not pair here.

No. Sigenergy's DC bi-directional EV charging module is not a standalone product, it only works as part of the full SigenStor system. It needs the SigenStor Energy Controller (the inverter) and a Sigenergy battery module connected together to function, so you can't leave the battery out and just run the inverter with the DC charger.

If you're after a standalone EV charger that doesn't need a battery, Sigenergy's AC EV charger can run on its own. For the DC bi-directional charger, plan for the full inverter and battery setup, and see the SigenStor Single Phase Energy Controller or SigenStor Three Phase Energy Controller for details.

For the SigenStor inverter on its own, no special Sigenergy accreditation is required, but you do need a licensed electrician for any above-ELV installation, the same as with other inverter brands.

If you're installing the full SigenStor system with a battery, that's a grid-connected battery energy storage system (BESS), and the installer needs to be SAA accredited. This is a general requirement for grid-connected battery systems, not something specific to Sigenergy. We can help match you with a suitable licensed and accredited installer for a complete Sigenergy install.

The standard Primo GEN24 is a solar-only inverter. It has a "PV Point" socket that can give you basic emergency power (up to 3kW) straight from your solar panels when the sun is shining, but it does not support connecting a battery unless you add the separate Fronius UP software upgrade.

The Primo GEN24 Plus has full battery support built in from the start, working with BYD Battery-Box Premium HVS and HVM batteries, plus full home backup during an outage. If you know you want a battery, even later on, the Plus is the simpler option.

Yes, Deye inverters can be run in parallel to build a larger system. The single-phase low-voltage models (the 5kW, 6kW, 8kW, 10kW and 12kW range) support up to 16 units working together. The three-phase low-voltage models (15kW and 20kW) support up to 10 units in parallel.

Parallel setups need to be designed and installed by a licensed electrician, who can confirm the right configuration for your switchboard and cabling. Have a browse of the SUN-6K-SG04LP1-AU or SUN-15/20K-SG05LP3-AU-SM2 product pages, or get in touch if you'd like help planning a multi-unit system.

SCERT stands for Selectronic Certified. It means a Fronius Primo or Symo inverter has been pre-approved to connect to a Selectronic SP PRO inverter-charger using what Fronius calls Managed AC Coupling. Together they form an off-grid or hybrid off-grid system, with the SP PRO managing the batteries and loads while the SCERT Fronius unit handles the solar.

You only need a SCERT model if you're building a Selectronic-based off-grid or hybrid off-grid system. For a standard grid-connected home with battery backup, a regular GEN24 Plus or Symo GEN24 Plus is the right choice instead. See the Symo 15kW SCERT for an example.

It depends on the model. The 48V models (SPMC480-AU, SPMC481-AU and SPMC482-AU) and the two larger 120V models (SPLC1200 and SPLC1202) are approved for grid connection in Australia under AS/NZS 4777.2:2020, and are listed on the CEC approved inverter list. These keep your home running if the grid goes down, and the same unit can also run a fully off-grid system.

The 24V models (SPMC240-AU and SPMC241-AU) and the SPMC1201 are off-grid only, with no path to export power to the grid. This is a hardware limitation, not a setting that can be changed. If you have a grid connection, choose one of the five grid-capable models instead.

Sungrow's SH-RS (single phase) and SH-RT (three phase) hybrid inverters are designed to pair natively with the Sungrow SBR high voltage battery system. BYD Battery-Box Premium HVM batteries are also reported to work with the high voltage models.

Because compatibility can vary by exact model and firmware, it's best to confirm your specific inverter and battery combination with us before you order. Have a look at the SH8RS or SH15T product pages, or contact us and we can help confirm the right battery pairing for your setup.

Yes, the Sungrow three-phase SH-RT and SH-T range (10kW, 15kW, 20kW and 25kW models) comes with the DTSU666-20 energy meter included, so you don't need to buy one separately.

This meter is what lets the inverter and Sungrow's iSolarCloud monitoring app see how much power your home is using, exporting and importing. Check the SH10RT-ADA or SH15T product page for full specs.
