About SUNGOLDPOWER SUNGOLDPOWER is a renewable energy company that is focused on designing & manufacturing inverter charger, solar inverter, solar panel and other green energy products. We have been in the inverter field for more than 10 years, and we aim to provide high quality inverters and good service to every customer! If you're trying to build solar system for your RV and off-grid home, we are your best choice ! 5000 watt DC 48 volt solar inverter’s conversion time between bypass and inverter is 10ms; Rated input voltage 110/120Vac, Frequency 50Hz/ 60Hz (Auto detection); Efficiency >95%(AC mode), Efficiency >92%(Inverter mode), PV voltage range 120-450Vdc, PV maximum output power 5000W. 4 Charging Modes Only Solar Charging: The battery will be the only charger source not matter the utility is available or not. PV Priority: Solar energy will charge battery as first priority. The utility will charge the battery when solar energy is not available. Utility Priority: The utility will charge the battery preferentially, and the battery will be charged by solar only when the utility is invalid. Hybrid Charging: The solar energy will charge the battery preferentially, the utility will charge the battery at the same time when the solar energy is insufficient. Parallel Support and Wirings When inverters are used in parallel , it should be noted that: 1. Each inverter should connect to PV modules separately.2. The settings of each inverter should be the consistent.3. The input connection of each inverter should be the same.4. Be sure to connect Current Sharing cable to units which are on the same phase. But please DO NOT connect Current Sharing cable between units on different phases. Otherwise, it may damage the inverters.5. Be sure the length of all battery cables need to be the same, and share the same battery bank.6. Please use the original Parallel Cable and Current Sharing cable. Do not make them by yourself. And Parallel cable and Current Sharing cable can not be parallel with the AC power wires and battery wires, need to cross or interval 1 meter distance between them. 5000W DC 48V solar inverter's Specification Notes: This solar inverter is for off grid system. It can be used in parallel.This pure sine wave inverter can only used for 48V solar system.Optional WiFi/GPRS remote monitoring need extra cost.Voltage setting logic:[15]＜[12]＜[04]＜[14]＜[35]＜[37]＜[05]＜[09/11]Maximum PV open circuit voltage 500Vdc, MPPT voltage range 120-450Vdc, Maximum PV input current 22A, Maximum PV input power 5500W. 4000W 12V 6500W 48V with WIFI/COMM 10000W 48V with WIFI/COMM 12000W 48V split phase 48V 100Ah Lithium Battery 48V 100Ah Lithium Battery Add to Cart Buying Options Add to Cart Add to Cart Buying Options Add to Cart Price $985.00$985.00 — no data $1,690.00$1,690.00 $2,799.00$2,799.00 — no data $1,325.00$1,325.00 Output Power 4000W 6500W 10000W 12000W 5120WH 5120WH DC Input 12V 48V 48V 48V 48V 48V AC Input 120V 120Vac/240Vac 120Vac/240Vac 240V ~ ~ AC Output 120V 120Vac/240Vac 120Vac/240Vac 120V and 240V ~ ~
