Solar Kit 3000W 24V 6400Wh/d
In this video we will present one of the most popular kits on our website, a system for homes isolated from the electricity grid, such as field huts or booths with a more intensive use in summers or weekends. This system is capable of supplying an average of 6400Wh / day or what is the same, in winter about 4.5 kWh per day and in summer we can go to about 9 kWh thanks to the greater amount of sun hours. Its maximum output power is 3000W instantaneous offered by your inverter and works with 24V batteries. This Kit is composed of:
• 4 polycrystalline solar panels from 335W to 24V, ERA SOLAR brand
• 4 stationary batteries model UZS600-6 with 600Ah and 6V of the Ultracell brand
• A 3000W 24V Must Solar charger inverter with 50A MPPT internal charge controller. This inverter is preinstalled in a metal sheet with the electrical equipment and the necessary protections to facilitate installation. Optionally a wifi monitoring kit can be installed.
• The system also includes a structure to install the panels on a coplanar surface, such as sheet metal, sandwich panel or concrete.
The accumulation of the system consists of 4 batteries of the renowned Ultracell brand, capable of storing a total of 14.4kWh of energy. These are stationary batteries, which need a little maintenance such as controlling their internal acid levels, which should always be between the minimum and maximum marks that appear on the front and periodically perform equalization charges, necessary for this type of accumulators
They are tubular plate batteries of great durability, composed of three separate vessels, as you can see, thanks to its transparent design. From the renowned Ultracell brand, they are perfect for small and medium-sized systems and a guarantee of reliability and durability. Feel free to contact us for personalized advice.
In its upper part, the battery incorporates two types of terminals for greater versatility: the screw type terminal and the vehicle type terminal. For convenience we will use the screw with nut to make the connection.
As for the inverter of this kit, it is a model of the Must Solar brand. It is pure wave with one with an output power of 3000W and works at 24V batteries. It incorporates a 50A MPPT regulator and a 30A AC battery charger inside. Thanks to its LCD screen and the keypad you can easily configure it and see all the system parameters.
The 4 solar panels are from the ERA SOLAR brand from 335W to 24V. They are polycrystalline modules that have a total of 72 cells and with a topology of 5 buses, which guarantee a better energy capture. All this also with an unbeatable value for money. It is a module of standard measurements in this type of power, in this case, they are 1956 millimeters high, 992 millimeters wide and 40 millimeters thick.
If you are going to do the installation yourself, we recommend that you purchase the electrical equipment kit to facilitate the process and to safeguard all the elements of your installation. This includes:
• A metal base, on which the inverter has been fixed
• Wiring to batteries and a disconnect to enable and disable the current flow
• The protections for the panel lines and the consumption output magnetothermal
• The wiring for the generator input, if you want to use it
• And all protected with the wiring duct and inside its corresponding box.
We hang the metal sheet on the chosen surface, making sure that there is a minimum of ventilation in the space and leaving the inverter at eye level approximately and close to the batteries, given the length of the cable towards them.
Before making the wiring connections of panels in their protections, connect the modules, in this case we make a serial-parallel connection. Given the production characteristics of the panels and the voltage supported by the MPPT controller, the modules must be connected in pairs. In series panels 2 to 2 and join the pairs in parallel. Because the panels have MC4 terminals at the ends of their wiring, the connection is greatly simplified.
The next step is to connect the batteries in series, thus joining the 4 6-volt batteries we will reach the 24v required by the system, since with the serial connection we add voltage, maintaining the intensity. We make use of the connection bridges, which will receive 3 units together with their Ultracell batteries and connect the positive terminal of one battery with the negative terminal of the next. In the remaining two terminals will be where we will connect the battery wiring that comes from the inverter. Go for it!
• Remove the nuts and washers from the terminals
• We introduce the bridge connecting our Ultracell batteries in series.
• We put the washers and nuts
• And with the help of a ratchet with number 13 key we tighten the connections. Make a firm connection but not with excessive force.
