Before making the decision to buy the battery, Know about Depth of Discharge!!! The battery’s Depth of Discharge ( DOD ) is the percentage of the battery capacity that can be safelydrained without damaging the battery. The more a battery isallowed to discharge, the shorter its lifespan. Deep cyclebatteries are designed to discharge 80% of their capacity but are recommended to choose a value of around 50%as a good trade-off between longevity, cost. For a deep cycle battery, 50% and for a lithium battery80% DOD is considered as good practice.

08.01.2022 Do you have a Growatt Solar Inverter No AC Connection Issue? Do you have a No AC Connection message being displayed on your Growatt Solar inverter? If so you’ve come to the right place for help! With the No AC Connection issue the red Fault light is on and the screen displays the No AC Connection message. This means that the inverter is not detecting any electricity from the power grid or from the switchboard and needs to be checked right away.... What can you do about a Growatt Solar Inverter No AC Connection issue? The first thing you should do is check if the Inverter AC Isolator (if applicable this would be beside your inverter) and the Solar Supply Main Switch in your switchboard are on. Check also that there has not been a power failure as a power failure would give the same message. If after checking the above the inverter still says No AC Connection, what you’ll need to do is contact a solar accredited electrician to come and have a look at your system and work out what’s causing the problem. They will check if you’re getting the right voltage from the electricity grid to the inverter. Still no AC Connection on your Growatt solar inverter? One more thing Ok so your electrician has checked the AC voltage at the inverter and it’s all good? There is one more thing that your electrician can try and that’s a small fuse inside the Growatt inverter. This fuse can blow and all that’s required is a replacement fuse be installed and away the Growatt goes! The following image shows the location of the fuse HAZARDOUS VOLTAGES MAY BE PRESENT INSIDE THE INVERTER EVEN WHEN TURNED OFF ALL ELECTRICAL WORK MUST BE PERFORMED BY A LICENSED ELECTRICIAN!!
