If you do not have a power supply or generator, the system can also operate normally, where the load is supplied by batteries and photovoltaic modules.Battery: The role of the battery is to ensure the normal use of electricity for the system load when the solar energy is insufficient and there is no electricity.Household load: Can be accessed to a variety of household and office loads, including refrigerators, lamps, televisions, fans, air conditioning and other AC loads.Battery type: 48V User-defined/Sealed(Default)/AGM battery/Flooded/Gel/Lithium iron/Ternary lithium battery.The PowMr Solar Inverter is suitable for 48V battery banks systems ONLY. Not following the minimum DC requirement may cause irreversible damage to the unit.The solar inverter components at the AC input/output, battery components, and PV components will produce high energy output. Make sure to connect the appropriate component to the appropriate labeled terminals.Be careful of the positive and negative poles. Reversing the poles may cause permanent damage to the inverter.The input terminals of the inverters have large capacitors connected to them. Once a positive and negative wire are connected to the terminals, it will complete the circuit, and commence drawing a heavy current momentarily.After the power switch is switched off, there is still high energy inside the solar inverter, do not open or touch the internal device, wait for the capacitance to be put off after the relevant operation.
