If this voltage gets exceeded, damage or even worse harm can result. New technologies established a new standard, to build PV systems with voltages up to 1000V (for special purposes in big PV power plants with central inverter topology even 1500V are used).

What is the maximum allowed voltage for a domestic PV system?

Domestic PV systems are growing in demand and size, and the recent update has reflected these changing conditions. Maximum allowable system voltage has persisted at 600 V for domestic dwelling systems since 2014, limiting design choices for designers.

What are the cell temperature limits for a photovoltaic system?

For the design of a photovoltaic system, the cell temperature limits established on the international market are minimum -10 °C and maximum +70 °C. Commonly these temperatures are used with the STC values of a module for the calculation of the extreme voltages.

Why do PV systems need a 1000v inverter?

New technologies established a new standard, to build PV systems with voltages up to 1000V (for special purposes in big PV power plants with central inverter topology even 1500V are used). This makes sense by causing lower losses (power / energy, voltage-drop) and gaining higher efficiencies (inverter).

Is 900W a good power supply for A 100/50 MPPT?

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?. That sounds a bit odd because it's quite a waste of power.

What is the efficiency of a PV module?

Modern PV Modules have an efficiency of 15% to 20% (often also given on the datasheet). While this percentage is converted into electricity the bigger “rest” (80% - 85%) of the irradiation is mostly converted into heat, meaning the PV cell (module) gets heated-up quite quickly.
