Off-grid solar omvormer QOLTEC 3500W model 53864 voor standalone fotovoltaïsche systemen

Description: Be energy independentThe performance of a photovoltaic system depends on the selection of the right inverter, or solar inverter. The inverter performs a key function in this system, converting the DC current generated by the photovoltaic panels into AC current used by household appliances. The off-grid hybrid inverter connects the photovoltaic system, energy storage and the grid.It uses excess solar energy to power consumers and charge the battery. When energy production is greater than current demand, the excess current can be transferred to charge LiFePO4, AGM, GEL or energy storage batteries, allowing energy to be stored for later use, such as at night or on cloudy days. The hybrid inverter can automatically switch to off-grid mode, supplying energy from the batteries.Why should you choose a hybrid inverter? Inverter with pure sine wave inverter type, automatic restart during AC power restoration, readable multifunctional touchscreen LCD display, 100A MPPT charge controller, option of mains or generator power supply, ability to change AC/Solar charger priority settings via LCD display, intelligent charger design for optimum battery performance, configurable input voltage range for home appliances and PCs via settings on the LCD display panel, configurable battery charging current depending on appliances and PCs via settings on the LCD display, cold start function, reserved communication port for RJ45, RS232. Maximize the possibilities with MPPT technologyThe battery charging inverter uses a state-of-the-art 100A MPPT charge controller to maximize the power drawn from the photovoltaic panels, using advanced maximum power point tracking technology. Having this feature significantly affects the efficiency of the photovoltaic installation-they can maintain high power even in low sunlight conditions. In addition, the controller controls the battery operation and charging process and protects the battery from damage.Multifunctional touch-screen LCD displayThe product is equipped with a multifunctional, easy-to-use LCD display with control panel. Facilitates monitoring of the entire photovoltaic installation. Allows you to configure the input voltage range for home appliances and personal computers or change the priority settings of the AC/Solar charger. In addition, the display records data and informs about failures, reacting accordingly if any of the parameters exceed the norm. If a fault occurs, the inverter shuts down. | Power: 3.5 | Number of phases: 1 | MPPT number: 1 | European efficiency: 94 | Efficiency (max.): 94 | Output current (max): 15.2 | Current (max.): 100 | MPPT voltage (min): 30 | MPPT voltage (max): 500 | Protection class: None | I/O connectors: None | Filters / protection: Overcharging | Filters / protection: Overload | Filters / protection: Circuit | Filters / protection: Overheating | Environment requirements: Working temperature: -10C ~ +50C Storage temperature: -15C do +60C | Color: White | Color: Green | Dimensions: (D/L x W x H): 330 x 278 x 98 mm | Weight: 4.35 | Accessories included: Solar inverter User manual Device installation protocol

How to use

Install the inverter in a dry, well-ventilated location following the manufacturer's installation guide. Connect the DC input to a compatible photovoltaic array or battery bank, ensuring correct polarity and secure connections. Connect the AC output to the intended load or distribution panel in accordance with local electrical regulations. Confirm the total continuous load does not exceed the 3500W rating and install protective devices (fuses, circuit breakers) where required. For final wiring and commissioning, engage a qualified installer or electrician.

Recommendations

Match inverter capacity to expected household or site loads and size the photovoltaic array and battery storage to meet daily energy requirements. Provide adequate ventilation and secure mounting, apply grounding and surge protection practices, and consult the QOLTEC user manual and applicable local electrical codes before connecting the system. For complex installations or persistent faults, contact a certified installer.
