Pure sine wave inverter,Can work no battery.Generate power from PV directly to supply load, even without battery PV to AC efficiency is much higher
The input voltage of home appliances and personal computers can be configured through LCD settings, the battery charging current can be configured according to the application, and the configurable AC/solar charging priority can be set
Auto restart while AC is recovering?WiFi communication is not included. Must be purchased separately.?
Overload/Over temperature/short circuit protection,Cold start function
Smart battery charger design for optimized battery performance

Y&H Off Grid MPPT Solar Inverter is a new all-in-one hybrid solar charge inverter, which integrates solar energy storage & means charging energy storage and AC sine wave output

It can be accessed to a variety of household appliances and office loads, power tools, industrial equipment, and electronic audio and video equipment, including refrigerators, lamps, televisions, fans, air conditioning and other AC loads

Advanced MPPT technology with an efficiency of 99.9%, output of pure sine wave. Output power factor 1.0
Designed with a LCD screen and 3 LED indicators for dynamic display of system data and operating status.
vailable in 4 charging modes: Only Solar, Mains Priority, Solar Priority and Mains & Solar hybrid charging.
Inverter running without battery.please know if the inverter does not connect battery, the PV voltage must be over 200VDC .
High PV input voltage range(120-500VDC) Recommended starting voltage greater than 150V
Overload/ Over temperature/ short circuit protection
Intelligent variable speed fan to efficiently dissipate heat and extend system life.
Smart battery charge design to optimize battery life

4 working modes+3 load output working modes
Battery Four Charging Mode?

CSO: Solar energy will charge battery as priority. Utility will charge battery only when solar energy is not available.
CUB: Utility will charge battery as priority. Solar energy will charge battery only when utility power is not available.
SNU (Default): Solar energy and utility will charge battery at the same time.
OSO: Solar energy will be the only charging source even if utility is available.
Three Load Working Mode:

SOL: Solar energy provides power to the loads as priority, then Battery, then Utility AC power.
UTI(Default): Utility will provide power to the loads as priority, then Solar and Battery power.
SBU: Battery power load first, then Utility.
CAUTION! Before connecting to AC input power source? please install a separate AC breaker between inverter and AC input power source.This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 32A for3.5KW and 50A for 5.5KW.

Warning:
SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY !!!
CAUTION --To reduce risk of injury, charge only AGM/FLD/Lithium/USER batteries. Other types of batteries may burst, causing personal injury and damage.
For optimum operation of this inverter/charger, please follow required spec to select appropriate cable size. It’s very important to correctly operate this inverter/charger.
This off grid solar inverter all-in-one does not support parallel operation, and does not support phase separation!(Single phase 240V AC /A Hot Leg, NOT Support 110V !!! )
Note: Inverter cannot output energy to utility. This is solar off-grid system.
Note: Inverter power rating must be 3-7 times the inductive load power. For example, the air conditioner is 700W. 700*3=2100W. It is recommended that you purchase a minimum of 2400W-3000W. to give the inverter enough buffer.
