Growatt 3-5kw off-Grid Home Solar Inverter SPF 3500 Es

Product Description Growatt Growatt SPF 3500 ES Off-Grid InverterThe Growatt SPF 3000 ES is an inverter that can operate both with and without a battery. The maximum input voltage is 450VDC.Integration of an MPPT charge controller optimizes charging and discharging of the battery, making it last as long as possible. Priority can be given to charging via the grid or the connected PV system.MonitoringThe system can also be remotely monitored using a WiFi or GPRS dongle. Parallel scaling is supported.Charge controllerThe MPPT charge controller lowers the voltage of panels to the required level to charge the battery. The current is raised with the same ratio the voltage is lowered.This continuously happens during the day to optimize the use of energy. This is dependent on the power of the sun, the angle and the temperature and health of the panels.The charge controller also makes sure the battery will not be overcharged, but also not fully discharged.Capacity expansionThe system's capacity can be expanded up to 30kW by combining a total of six of these units in parallel operation. Product Parameters  Datasheet SPF 3500 ES SPF 5000 ES Battery Voltage Lithium/Lead-acid INVERTER OUTPUT Rated Power 3500VA/ 3500W 5000VA/ 5000W Parallel Capability Yes, 6 units maximum AC Voltage Regulation (Battery Mode) 230VAC ± 5% @ 50/60Hz Surge Power 7000VA 10000VA Efficiency (Peak) 93% Waveform Pure sine wave Transfer Time 10ms typical, 20ms Max SOLAR CHARGER Maximum PV Array Power 4500W 6000W MPPT Range @ Operating Voltage 120VDC ~ 430VDC Number of Independent MPP Trackers/Strings Per MPP Tracker 1/1 Maximum PV Array Open Circuit Voltage 450VDC Maximum Solar Charge Current 80A 100A AC CHARGER Charge Current 60A 80A AC Input Voltage 230 VAC Selectable Voltage Range 170-280 VAC (For Personal Computers) ; 90-280 VAC (For Home Appliances) Frequency Range 50Hz/60Hz (Auto sensing) PHYSICAL Protection Degree IP20 Dimension (W/H/D) 330/485/135mm 330/485/135mm Net Weight 11.5kgs 12kgs Packaging & Shipping   Company Profile Anhui Wingo Technology Co., Ltd. has set up two sole-funded companies in Heifei one Jointed Venture in Anhui province successively since 2020.Wingo is able to provide customers with annual capacity of 300MW solar cells,400MW solar cells modules and 60,000 sets of solar power systems.FACTORY DIRECT SOLAR INVERTER WITH TIER 1 BRAND!FACTORY DIRECT SOLAR PANEL WITH TIER 1 BRAND!  FAQAre you a factory or a trading company?We are the manufacturer of solar panel and storage battery.
