About Photovoltaic panels exceed maximum power
PV voltage of your MPPT 100/50, which is 100V, you don't do any harm to them. The MPPT limits the output to its maximum current of like 50A (or what you have set via VictronConnect). But I wonder why you want to hook up 900W to a 700W MPPT?.

The Wattage rating of a solar panel is the most fundamental rating, representing the maximum power output of the solar panel under ideal conditions. You’ll often see it referred to as “Rated Power”, “Maximum Power”, or “Pmax”, and it’s measured in watts or kilowatts peak (kWp).
PV inverters are designed so that the generated module output power does not exceed the rated maximum inverter AC power. Oversizing implies having more DC power than AC power. This increases power output in low light conditions. You can install a smaller inverter for a given DC array size, or you can install more PV modules for a given inverter.
As an example, if the temperature coefficient is -0.5% and the panel was tested at 25°C, then the output power of the panel will decrease by 0.5% with every degree of temperature increase. If the temperature of the panel reaches 45°C, the maximum output power would be reduced by 20x0.5%=10%.
Solar panel efficiency is the amount of sunlight (solar irradiance) that falls on the surface of a solar panel and is converted into electricity. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 23%.

6 FAQs about [Photovoltaic panels exceed maximum power]
What is a maximum system voltage rated solar panel?
Conversely, if the cell temperature falls below 25°C, the voltage will exceed the rated value, leading to an increase in power output. The Maximum System Voltage rating indicates the highest voltage that a solar panel can safely handle when it is part of a larger system.
How efficient are photovoltaic panels?
Due to the many advances in photovoltaic technology over recent years, the average panel conversion efficiency has increased from 15% to over 23%. This significant jump in efficiency resulted in the power rating of a standard-size panel increasing from 250W to over 450W.
Can solar panels reach 100 °C under partial shadowing?
Bypass diodes decrease power loss in reverse-biased shaded cells; however, solar panel hotspots cannot be prevented. Therefore, even with bypass diodes, monocrystalline-silicon panels may reach 100 °C under partial shadowing . 2.1.2. Corrosion of a PV module Moisture entering solar PV module corners corrodes the bus bars.
Is Household PV power underestimated?
Household PV power is underestimated by up to 22% when using 15 min averages. Fluctuations of household PV systems exceed those of both irradiance and PV parks. Clear-sky conditions do not represent the worst-case for PV grid-integration. Bimodality of irradiance requires temporal resolution in order of seconds.
Can a PV module produce a full rated voltage?
As the irradiance value continues to increase, so does the voltage — but at a much slower rate. Therefore, for the purposes of this article — and your design methodologies in general — it is safe to assume that if there is ambient light, the PV module has the ability to produce its full rated voltage.
What happens if a PV array voltage is outside MPPT?
When a PV array voltage is outside an MPPT voltage range, the inverter is not able to maximize the performance of the system. To most easily design an oversized PV array, Sunny Design is the simplest tool since it can provide warnings if a design will exceed an inverter’s critical input parameters. 2.
