Great thanks for the feedback.

Is your geyser permanently connected to utility or do you switch off from solar at 13:00? I also have a geyserwise running but my whole house runs through the 2 inverters so if geyserwise switches power on to the geyser it can use solar/inverter. Do you have some more information on how to use a contactor and connect it to the geyser and inverter? Thanks,

I'm thinking to switch between grid and batteries twice within 24 hours to cater for certain loads. Is it advisable to send commands to the inverters to switch (I know it's a controlled switch) multiple times a day and could there be long term damage to appliances, tv's etc. as do notice a switch from solar/battery to grid does makes my tv turn of and on again? Thanks,

Thanks, valuable information and I think we rethink how we use the geyser. I'm using the ICC software to monitor. I'm going to use the battery setting to set the Time for Control to change over to Eskom before the geyser kicks in in the late afternoon and switch back to batteries later at night. Unfortunately on ICC I can only set it once and would have liked to switch back to Eskom early in the morning for a second time before the geyser kicks in for the second cycle. I guess the one option is to set the Axpert voltage setting 12 to a higher number then Eskom will have to kick in (because of the voltage drop) and once the geyser starts early in the morning if the house was running on batteries for most of the night? Second option is to set Geyserwise not to warm the geyser in the morning and let the sun warm the geyser for the day. Third option is disconnecting the geyser from the inverters and only to Eskom The reason I kept it one the inverters is because I have 2 5kva inverters which has captivity to run my whole house. I like the MiniGeza (and the first time I seen it) for warming water in a bucket, but it still uses 2000w which will a be a high load on batteries.

Thanks for the feedback. I prefer not to charge the batteries using the gird and will stay on solar charging for now. I currently have 12 270-320w panels and 4 200Ah batteries which will last me the night at around 50% DOD if no real high load was put on the system. My biggest load is the geyser. I have the geyser on it own solar and using Geyserwise to manage when the geyser will use grid or battery. The load happens when the geyser needs a 'top-up' around late afternoon if the geyser was used often during the day and solar was not able to warm the geyser enough, and mostly in the morning before we shower. Is it wise to let the geyser run on solar/battery when required(I only have two cycles in 24 hours for warming the geyser)? When the load is too high and the voltage drops it does switch back to utility. Thanks,

Hi All, If the Axpert inverters are set to SBU (setting 1) and OSO (setting 16) and the Inverters switch over to utility during the evening because of setting 12 and a high load. If the load drops and If you force the utility to not be available it jumps back to battery. If you enable utility again it goes back to utility, should it not stay on battery because the voltage is above setting 12 or is it because the batteries have not been charged back to the voltage in setting 13?
