Growatt SPF 3500ES photovoltaic inverter 3.5kW 48V

Growatt SPF 3500 ES inverter 5 kW The Growatt SPF 3500 ES inverter is the optimal choice for so-called island systems without an available distribution network - a generator and/or battery can be connected to the unit as a backup energy source. This is a hybrid inverter with a sine wave output ideal for home and small commercial systems. The built-in MPPT controller can handle up to 4.5 kW of PV arrays with a maximum open circuit voltage of 450 Voc. It can work with both lead-acid and Li-ion batteries. Of course, there are RJ-45 ports for CAN/RS-485 communication with BMS LiFePO4 modular batteries of brands such as Pylontech, WECO, Seplos, etc. The inverter can also be operated without a battery, provided there is an active connection to the distribution network. In SUB operating mode, the inverter monitors the load power consumption and the output of the available photovoltaic source, and any missing energy is supplemented from the DS. The device allows setting a bypass, which in the event of a battery or PV array disconnection, connects the inverter output to the DS within 10 ms to avoid power interruption. It also supports UPS mode with a switchover to pure battery operation within 10 ms. By connecting inverters in parallel, a total system power of up to 30 kW can be achieved. The inverter can be retrofitted with a Wi-Fi/LAN communication module for remote control and monitoring. Features: Integrated MPPT solar controller Equalizing charging function Ability to operate with or without a battery Input photovoltaic voltage up to 450 VDC Configurable priority of grid or solar input With the possibility of remote monitoring via Wi-Fi Support for parallel operation to expand capacity up to 30 kW PV and grid supply the load together if PV energy is insufficient Flexible planning of charging and discharging times by the inverter Active cooling fans with speed control according to the inverter load The inverter comes with a free Wi-Fi module for wireless communication and monitoring. A big advantage is easy installation and intuitive control with inverter settings via a clear LCD display, PC or simply a mobile phone. When operating the inverter in Solar Priority mode and when operating without a battery, the inverter behaves as a so-called "hybrid", there is a possibility of electrical energy overflows into the distribution network. To eliminate these overflows, use the SBU Battery Priority mode, where when there is a lack of energy in the battery, it switches to bypass. Growatt is one of the world's largest manufacturers of photovoltaic inverters and is even a leader among suppliers for residential use. It currently sells its products in 160 countries around the world and has 41 local representatives.
