Hello,
Do you think we can set this GTI in solar operation on panels of 24 V with Umpp of 36 V and a Uoc of 43.58 V DC?
Is it better to retranscribe the Impp / Vmpp curve?
Configuring a Mastervolt Windmaster 500
The information on Mastervolt's Windmaster 500 is missing, just read carefully:
http://www.solar-kit.com/WebRoot/StoreL ... 25ENFR.pdf
Since the voltage range of the full-power GTI starts at 65V, with the max solar panels of power at about 25V to 30V there is no compatibility for panels of power greater than half the 500W, ie max 250W for have 65W / 2 = 32,5V, very much about.
The linear curve of PDC versus VDC, is adjustable with the max of 120V reducible to 65V at best.
So the Mastervolt Windmaster 500 will only work halfway with this solar panel.
Less than doubling the voltage with serial connection from 2 to 4 to double the voltages at least.
This Windmaster 500 from Mastervolt is designed for wind turbines with this characteristic of linear voltage and power, which is never linear for a real wind turbine but cubic (Betz) with saturation.
The information on the instructions of Mastervolt Windmaster 500 are a little thin but much more than for other brands.

Power Curve
The Windmaster 500 converts DC power
from a wind turbine to the AC grid. This conversion
is based on a linear curve with a voltage
starting and operating voltage
maximum (see 1 scheme). These parameters
can be adjusted and optimized by the supplier
the system for use with a wind turbine
in particular. When the DC voltage reaches the
threshold voltage to start the Windmaster, this one
starts a countdown of 5 seconds before
to supply energy to the network.
CC interface
The CC interface is here to protect the Windmaster
500, and should provide the following:
• Protection against voltage spikes;
• Surge protection, max
150VCC (*);
• Disconnect switch (if applicable).
(*) Mechanical or electrical protection against
overvoltages can be integrated into the wind turbine.
Mastervolt can not be held responsible
for:
• Possible errors in this manual
and their consequences

For the curve, what do you recommend me?
It is necessary in principle to choose close to the actual curve of the panels P (U), to be drawn, which has nothing to do with a wind turbine with I (proportional to the light) almost independent of V = U up to U max, to see the photoelectric effect curves.
UImax decreases with luminous intensity.
P (U) is thus close to a slope line proportional to the solar light flux, up to a little before Umax, to decrease abruptly very quickly to zero, to Umax at I = 0.
This is not at all like the Windmaster 500, which does not descend and has a fixed slope regardless of wind or light.
It should look for Pmax whatever V is empty by increasing the current to P max, and measure the P (U) curve automatically in the learning phase.
Is UDC UDC empty with Preel = 0 or PDC UDC chosen?
This curve is too vague in its definition.
But the program is likely to be very different for wind turbine U = Uvide-RI and Uvide decreasing with I by braking the wind turbine and solar panels with I fixed according to U up to U max.
It is possible to try the low U slope straight possible at u max panels.
It lacks a lot of specific information.

A life size, I changed a little the parameters of the curve because it was difficult to start now it works on panels.
It's amazing the difference with the other GTIs. This one does not make a single noise. We do not wait for the dizziness.
For those who consume 60- 70 Watts empty. You have an idea where this might come from. It's weird.
