Normally, the inverter by default integrates some basic power management functions which are required by local gridding regulations.
A manual method to get more power management function can be realized by our dataloggers (Wifi Stick/AiCom). Log into relevant APP/webserver/Cloud, you can set the active/reactive power value, or fixed power factor, reactive power curve to control power.
Through some 3rd party control device, e.g. RRCR (radio ripple control receiver) or DRED connected to AiCom, an inverter can receive the instructions in real-time and control the output power automatically.
For more details, please refer to user manuals or contact our service for technical support.

Wifi Stick: The stick is installed on bottom of inverter house by plug-in connection. One stick can be connected with one inverter.
AiCom: Installed outside of a Solplanet inverter. The AiCom connects to an inverter via RS485 and to a router via WiFi or LAN. One AiCom can be connected to a maximum of five inverters.

Yes, Solplanet inverters support third-party data loggers like Solarlog, Meteocontrol, and Solarman. For large-scale PV installations, we can offer our protocol to a third party to be used to develop their own customized monitoring solution.

No, the AISWEI Cloud does not obtain or record weather data like irradiation levels, temperature, or wind speed. If you need to monitor the weather to support your PV installation, you can either purchase an independent weather station or use a third-party solution (like Solarlog, Meteocontrol, and Solarman).

Yes, you can. However, because of outdoor weather conditions, an AiComm must be installed within an IP65-rated enclosure.

No, our inverters do not support local monitoring. Our monitoring solutions (either a GPRS stick, WiFi stick, or AiComm) upload inverter data to the Solplanet Cloud and that requires a stable and reliable internet connection. If required, we can supply our communications protocol to our customers so they can develop their own monitoring systems.

Your privacy is one of our top concerns and we take it very seriously. Once you permit us to collect your data, it will be stored in compliance with privacy laws in your country. 

If you have concerns about how we collect and store your data, please don’t hesitate to contact your local Solplanet team.

You can find the installation manual for the AISWEI Cloud here.

The AISWEI Cloud app is available for both the iOS and Android platforms. You can download the app for your platform from either the App Store or Google Play.

This is a permanent fault. Disconnect the inverter from the utility grid and the PV array and reconnect it after 3 minutes. If this fault is still being displayed, contact your local service team.

This fault relates to power distribution. If you see this error code, open the inverter box and check the power distribution to see if a fuse has been damaged.

Open the box and check the power distribution, see if the signal cable of PV1-SPD and PV2-SPD has disconnected. If the fault still occurs, please contact our service department.

Check the open-circuit voltages of the strings, make sure it is lower than the Max. DC input voltage of the inverter; If the input voltage lies within the permitted range, and the fault still occurs, maybe the internal circuit has broken, contact our service department.

Disconnect the inverter from the grid and the PV array and reconnect after 3 minutes. If this fault is still being shown, contact your local service department.

This fault relates to the maximum operating temperature for your inverter. If you see this error code, check to ensure that the airflow to the heat sink is unobstructed and check to make sure the ambient temperature around the inverter isn’t too high.

Check the PV array’s insulation to ground and make sure that the insulation resistance to ground is greater than 1 MOhm. Otherwise, make a visual inspection of all PV cables and modules.
Make sure the grounding connection of the inverter is reliable. If this fault occurs often, contact your local service team.

Check the open-circuit voltages of the strings and make sure it is below the maximum DC input voltage of the inverter. If the input voltage lies within the permitted range and the fault still occurs, please contact service.

Make sure the grounding connection of the inverter is reliable.
Make a visual inspection of all PV cables and modules. If this fault is still shown, contact service.

Absolutely! We manufacture efficient, reliable, and user-friendly single and three-phase hybrid inverters tailored for solar installations in residential, commercial, and industrial settings. Explore our full product catalogue here.

Surge protection is a common consideration in inverter design to safeguard the equipment from voltage spikes and surges. Specific details about the surge protection features of Solplanet inverters would depend on the specific model and product specifications. It’s recommended to refer to the product documentation and user manual or contact Solplanet directly for accurate and detailed information about the surge protection capabilities of their inverters.

Solplanet inverters handle high ambient temperatures very well. They will automatically decrease power output to protect themselves from overheating. Our detailed installation and operating instructions provide specific power reduction curves for each inverter model.

Yes. For all Solplanet inverters, through our datalogger of AiCom and defined smart meter, you can get 0-export function by setting on datalogger’s webserver/APP/AiSWEI cloud.
For Solplanet residential inverters, you also can have export control solution through connecting the defined smart meter directly to the inverter via RS485 and enable this function on APP.
For more details, please refer to the user manuals or contact our service for support.

Yes, it can. The PV array can typically be oversized by 150% depending on location and site irradiation levels. But note that excessive PV array oversizing can result in wasted money and a negative impact on the reliability of the inverter. If you have questions about oversizing a PV array, please contact your local Solplanet office.

Solplanet inverters can be used with thin-film solar panels, but this would be a pretty rare setup. Thin-film solar panels are usually better suited for portable devices. Solplanet inverters are stationary and are designed for traditional PV arrays in residential, commercial, and industrial situations. 

However, some thin-film panels on the market do not have to be adhered to a surface and in these cases, a Solplanet inverter will operate correctly.

No, they cannot. Solplanet inverters are designed to be on-grid inverters. The AC side of the inverter should be connected to the utility grid at all times. There are no settings to allow the inverter to operate in an “off-the-grid” or “island” mode. Solplanet cannot guarantee correct operation in off-grid applications and will not warranty any damages caused to the inverter(s) or the PV plant caused by off-grid use.

Solplanet produces only non-isolated (transformerless) inverters. The transformerless inverter is the most common in the residential and commercial market because it usually has the highest efficiency, lowest cost, smallest size and lightest weight compared to isolated (transformer) inverters.

Yes, all Solplanet inverters are equipped with a DC switch for smooth and uninterrupted power distribution.

In the simplest of terms, you’ll want to match your inverter to the wattage of your PV array. For example, if you have a 3000-watt PV array, you’ll need a 3000-watt inverter at a minimum. You’ll also need to consider things like the rating of your PV array, the maximum size of the installation, and even your geographical location. But don’t worry, it’s not as complicated as it seems. 

Contact our technical support team for help determining which Solplanet inverter is the best match for you.

Check the fuse and the triggering of the circuit breaker in the distribution box.
Check the grid voltage, grid usability.
Check the AC cable, grid connection on the inverter. If this fault is still being shown, contact service.

Check the grid voltage and grid connection on the inverter.
Check the grid voltage at the point of connection of the inverter. If the grid voltage is outside the permissible range due to local grid conditions, try to modify the values of the monitored operational limits after informing the electric utility company first. If the grid voltage lies within the permitted range and this fault still occurs, please contact service.

Frequent power fluctuations could cause this fault so check the grid frequency and make a note of how often major fluctuations occur. If major fluctuations are frequent, try to modify the operation parameters after informing the local grid operator.

Check the open-circuit voltages of the strings and make sure it is below the
maximum DC input voltage of the inverter. If the input voltage is within the permitted range and the fault still occurs, it might be that the internal circuit has broken. Contact service if the problem has not been solved.
