The inverter will automatically decrease its output power to protect itself from overheating. You can find the inverters power reduction curve in the installation and operating instructions.
The DC switch is an optional feature. Please check your local PV regulations to determine whether you require an inverter with or without a DC switch. For Europe, our inverters are equipped with a DC switch as standard. For Australia the local regulations require the use of an external DC switch therefore a Zeversolar inveter without a DC switch is in this case accepted. Please contact your local Zeversolar sales representative or authorised distributor for further information.
Zeversolar produces only non-isolated(transformerless) inverters. The transformerless inverter is the most common inverter in the residential and commercial market and usually has a higher efficiency, lower cost, is smaller in size and lighter in weight in comparison to isolated (transformer) inverters.
Zeversolar only produces non-isolated on-grid inverters. At this point in time we do not produce any type of off-grid inverter, battery inverter or hybrid inverter.
Zeversolar’s inverters are on-grid inverters and such as the AC side of the inverter should be connected with the utility grid. There are no settings that allow the inverter to operate in “off-grid” or “island mode” mode. Zeversolar cannot guarantee correct operation in off-grid applications and will not warrant any damage to the inverter or the PV plant that may be caused under “off-grid” conditions.
We do not provide local monitoring. Zeversolar's monitoring solution consists of either a Combox/Zevercom/Zevermanager which uploads the inverter data to our Zevercloud online monitoring portal which requires a reliable internet connection. We can provide our communications protocol to our customers to develop their own monitoring system. Third party monitoring devices and software such as Solarlog can be used with our Zeversolar inverters.
Yes, but it must be installed in an IP65 rated enclosure.
Zevercloud does not obtain or record weather data such as irradiation, temperature or wind speed. If you require to monitor weather data, it is possible to either purchase an independent weather station or you can use an existing third party solution from suppliers such as solar-log/ meteocontrol/ solarman which can communicate with our inverters.
No, Zeversolar and SMA use different communication protocols therefore Zeversolar inverter's cannot communicate with SMA's products (including SMA's string inverter, Sunny island, Data logger, fuel save controller etc.).
Yes, Zeversolar inverter's support dataloggers supplied by Solarlog, meteocontrol and solarman's. In addition, for large PV plants, we can offer our protocol to a third party company to develop their own customised monitoring solution.
Combox: Installed inside zeverlution single phase inverter, internet connection with WiFi option, one Combox can be connected with one inverter.
Zevercom: Installed externally to Zeversolar inverter's, cable connection with inverter, internet connection with WiFi (optional) or via LAN cable, one Zevercom can be connected to a maximum of five inverters.
Zevermanager: installed externally to Zeversolar inverter's, cable connection with inverter and router, one zevermanager can be connected to a maximum of 50 inverters.
You can design your PV system with Zeversolar’s free PV planning software Zeverplan. It is an online web based planning tool which can be found by typing www.zeverplan.com into your web browser. A downloadable version is not available.
Zeversolar inverter's cannot be used with thin film modules which require a functional earth on either the positive or the negative DC conductor, in these cases we suggest using an isolated (transformer based) inverter. Our non-isolated (transformerless) inverters are normally designed for silicon solar modules. However, there are thin film solar panels that do not require a functional earth and in these cases a Zeversolar inverter will operate correctly. Please consult with your thin film module supplier before confirming your PV plant design.
Yes, the PV array DC capacity can exceed the inverter AC capacity. A typical rule of thumb is that the PV array can be oversized by 20%. This is dependent on location and site irradiation levels. Excessive PV array oversizing can impact on the inverters reliability, if you are in doubt please contact your local Zeversolar technical expert.
Through the radio ripple control receiver (RRCR) input on the Zevermanager, you can set and adjust the PV plant output according to grid operator requirements. In Germany this is widely used to control the PV plant output in 4 stages 0%, 30%, 60% and 100%. You can also log into the webserver of the Zevercom/Zevermanager to set active/reactive power, set a fixed power factor or set a reactive power characteristic curve. The PV Plant will control the output power automatically according to the settings.
Yes, through Zevercom/Zevermanager and smart meter SDM630DC/SDM630CT. You can log into the webserver of a Zevecom/Zevermanager and set “limit output power based on energy meter reading” at 0W. Zevercom/Zevermanager can monitor the PV power fed to grid from the smart meter, and reduce the output of inverter to ensure that the PV power does not exceed the load consumption.
