Can I use thin-film modules for AISWEI Inverter's?
A
AISWEI inverter 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 AISWEI inverter will operate correctly. Before designing your plant, please consult with module supplier and our service for technical support.
Q
Can I oversize the PV array with respect to the Inverter Capacity?
A
Yes, the PV array DC capacity can exceed the inverter AC capacity. The value of DC/AC ratio for each type of inverter is listed in its datasheet. 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 will waste money and cause some impact to inverter’s reliability. If you are in doubt of oversize designing please contact your local AISWEI technical expert.
Q
How to realize the Power Management Functions?
A
Normally, the inverter by default integrates some basic power management functions which is required by local gridding regulations.
A manual method to get more power management function can be realized by our dataloggers of Stick/AiCom/AiManager. 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 or AiManager, inverter can receive the instructions in real time and control the output power automatically.
More details please refer to user manuals or contact our service for technical support.
Q
Does AISWEI have an 0-Export Control Solution?
A
Yes.
For all AISWEI inverter, through our datalogger of AiCom/AiManager and defined smart meter, you can get 0-export function by setting on datalogger’s webserver/APP/AiSWEI cloud。
For AISWEI residential inverter, you also can have export control solution through connecting the defined smart meter directly to inverter via RS485 and enable this function on APP.
More details please refer to user manuals or contact our service for help.
