As one does not always have the necessary electrical knowledge to carry out an installation of an isolated photovoltaic solar kit without help, we are going to start by emphasizing that the installation must always be carried out by a person who has a minimum knowledge of electricity (since there is danger due to electrical risk, which can easily cause personal and/or material damage) and also, since not all equipment is the same, we always recommend reading the equipment manuals before installing them.
Basic tips and recommendations to be clear about before proceeding to install an isolated photovoltaic installation
In addition, for those of you who, even if you have knowledge of electricity, but have never installed an isolated photovoltaic solar energy installation, here are a series of basic recommendations to follow:
- Never place electronic equipment on top of the batteries vertically, because the gases that the batteries can produce during use can attack and end up damaging the electronics.
- The panels can never be connected to the regulator if the regulator is not connected to the battery: Therefore, before connecting the panels, the regulator must be connected to the battery and before disconnecting the battery, always disconnect the panels first.
- Always try to minimize the wiring distances, especially between the regulator and the batteries and between the batteries and the inverter: recommended distance in both cases of 1m of wiring, enough to separate us a little horizontally from the vertical of the batteries. The wiring section to be used in each case depends on the maximum intensity that will pass through the wiring and normally always appears in the equipment manuals.
- It is recommended to install a quick disconnect element, circuit breaker type or fuse (in the positive cable) of equal or more amperes than the sum of the amperes (Icc or Isc) of the panels that will be connected to it, at the entrance of the panels to the regulator. in parallel.
- It is recommended to put a fuse between the batteries and the inverter on the positive cable and with equal or more amps than the nominal consumption of the inverter at maximum power.
- In the consumption output of the regulator (if the regulator has that output) only consumption can be directly connected to 12, 24 or 48V (depending on the battery system that we have in each case).
- Always connect the inverter directly to the battery and never through the charge regulator.
We hope we have helped you with these basic installation tips.
