50-300L Thermal DC 72V Solar Hot Water Heater Working with Solar PanelSolar water heater features:(1) Large screen temperature indication with heating indicator light, working status at a glance.(2) Microcomputer control, heating and insulation automatic control.(3) The inner liner is made of high-quality steel plate and equipped with a liner protection device, which is anti-corrosion and pressure-resistant and durable.(4) It has multiple safety protection functions such as leakage protection, anti-dry protection, over- temperature protection, over-pressure protection, and leakage warning.(5) The insulation layer is foamed with thickened polyurethane, which has good heat preservation effect and saves energy.(6) It has a wide range of water pressure and large capacity, and can be used for water at the same time.Solar water heater specification:TypeGF-50LII(PV)(DC Only)GF-60LII(PV)(DC Only)GF-80LII(PV)(DC Only)GF-50L(PV)(ACDC)GF-60L(PV)(ACDC)GF-80L(PV)(ACDC)GF-100L(PV)(ACDC)GF-200L(PV)(ACDC)The tank capacity (L)506080506080100200The tank materialenamelenamelenamelenamelenamelenamelenamelenamelPV peak voltage (Vpmax)DC( 1-150V)DC( 1-150V)DC( 1-150V)DC( 1-150V)DC( 1-150V)DC( 1-150V)DC( 1-150V)DC( 1-150V)*2PV open circuit voltage (Vop)84841268484126126126*2PV peak power (W)500w or above 500w or above 800w or above 500w or above 500w or above 800w or above 800w or above 2000w or aboveGrid Power (V)   220-240V220-240V220-240V220-240V220-240VPower frequency (Hz)   5050505050Rated power consumption W/H   20002000200020002000*2(MPa)Nominal pressure (Mpa)0.80.80.80.80.80.80.80.8AC.Temperature range (ºC)   30--7530--7530--7530--7530--75DC.Temperature range (ºC)≥75ºCOFF/≤65ºCON       The extermal diameter (mm)390390470390390470470520Outer barrel length(mm)6959007807859007809151520Insulation thickness (mm)2525253535353525Insulation density (Kg/m³)3434343434343434Insulation materialEnvironmentally friendly polyurethane       24hε) Natural energy consumption coefficient (ε)0.70.70.70.580.580.580.580.7Energy consumption  level  Super grade2 Super grade 2 Super grade 2 Super grade 1 Super grade 1 Super grade 1 Super grade 1 Super grade 2Hot water output(μ)80.00%80.00%80.00%80.00%80.00%80.00%80.00%80.00%Energy efficiency Super grade2 Super grade2 Super grade2Super grade 1Super grade 1Super grade 1Super grade 1Super grade 1Product Details:Special warning:1. This electric water heater must have a safe and reliable grounding device.2. This machine must be installed with a safety valve at the water inlet.3, must be filled with water before powering up, when adding water should open the water inlet and outlet simultaneously,after fill up the water,it will flow out from the water outlet.4. The water inlet and outlet of the water heater cannot be closed at the sametime.5. It should be cleaned once for half a year.Method: first close the tap water valve, then unscrew the drain port (be careful to avoid hot water) and then open the water outlet valve, the water in the machine will flow out from the drain outlet. After emptying, open the tap water valve and rinse it several times until the water that flows out is free of impurities.Daily mainternance:1, Always pay attention to the pipe joints with or without water leakage, if any, timely treatment.2. Regularly (one week) check whether the leakage test plug of the leakage protection plug power cord  "test power off " button can be operated.3. Always observe whether the safety valve can be properly relieved.4.  Always  check  if  the  grounding  of  the   power  socket  is  firm  and  meet  the   power  supply requirements.5, Rigorous wethand plugged in the power plug, the power plug should be unplugged when not in use for a long time.6. Due to the different water quality and hardness of different areas, the water heater should be drained regularly to discharge the sediment at the bottom of the tank. To empty the water heater, first close the tap water valve, then unscrew the drain port (be careful to avoid hot water), then open the water outlet valve, the water in the machine will flow out from the drain outlet. After emptying, open the tap water valve and rinse it several times until the water that flows out is free of impurities.7. The safety valve should not be replaced at will. Only the original parts can be used. The pressure of the safety valve should not be adjusted by itself. At least once a month, the safety valve handle is swayed (unscrew the fixing screw before shaking) to see if there is water Discharge, if it can not be discharged, notify the manufacturer or the manufacturer of the service point to repair.Common fault and approach:  FaultphenomenonCause AnalysisApproachWater   discharging is cold water(The work indicator is off)1. The  reset  button on the  plug or the power switch is not pressed2. Power fuse off or air switch jumpor leakage protection switch action3. Power supply line blackout4. Poor contact in the power outlet   5.  The  lowest  temperature  control state
