February 11, 20242 yr Hello, I was told I can use the smart input of the Deye to heat up the geyser using PV. My understanding of how it works: When the batteries reach a certain % then the smart input is triggered even though there is no Eskom As long as there is sufficient PV to heat the geyser the power can be consumed. Question: Does the geyser have to be connected at essential when using the smart input? What happens during normal functioning whereby there is Eskom and wish to use this input to heat the geyser? Thank you for your input...

Thank you for your input... AFAIK the geyser is not connected to any of the 2 main outputs but to the smart port. This being the only way to dump this power available from excess PV. Grid does not affect it as the battery level is the trigger to output power to the smart load port or not. Users of this inverter will confirm the above.
February 11, 20242 yr Author So this means if there is no PV being generated (rain or cloudy day) I will not be able to heat the Geyser using Eskom?

You can, when there is grid. Usually the DB is split up into non-essential and essential loads, with the non-essentials not being supported when the grid is down. So if your geyser is on one of those circuits, it can use grid when there is grid.

The smart load is not on essential or non essential. You have a setting to always have the geyser on which implies using grid if available and not only PV. It is not called smart load just for a name. It is smart. This port is bi-directional. As a non user of this inverter I stand to be corrected. Edited February 11, 20242 yr by Scorp007

Thats interesting indeed..will need to do more reading on this port..

February 11, 20242 yr Just read the explanation in the manual which outlines the parameters of operation and the logic of the SMART port. It is also essential to note that when one utilizes the SMART port for supplying a geyser or other load, one must incorporate separate protection and EL for such equipment.

Switch on when grid is not present however PV is there and battery SOC trigger level is met Correct, if ‘Grid’ is ticked it’ll be on regardless when there’s grid. When no grid, the parameters you specify here will apply. Also note that the PV Power value on this screen is currently-in-use solar power (as opposed to total available power); so this value would be your household’s base load to trigger the port when there’s PV. You can’t specify the power rating of your geyser in this field unfortunately. Otherwise, this should do what you’re after.

You can’t specify the power rating of your geyser in this field unfortunately. The user determine/program the threshold. The value specified would be available PV, in excess of the base load required for normal operation. It will be worth one's while to have extra PV panels installed to fully utilize the SMART port functionality Edited February 11, 20242 yr by CobusK Added PV panels...

Approach the GEN PORT now as AC feed to a secondary or localized DB which houses the EL and MCB that feed the SMART LOAD dependent equipment (geyser, pool pump, etc). Keep normal AC wiring practices in mind w.r.t wire size and reticulation. Program the inverter You can also wire in a change-over capability if need be Edited February 11, 20242 yr by CobusK Change-over

It will still be Escom, but managed by the Inverter settings if the 'On grid always on' tick box is selected. If not selected, the Inverter will manage the Smart Load subject to the conditions determined by the user re. 1. PV and 2. SOC - in that order if the SMART LOAD option is selected, the Gen Port is converted from an AC Input (default) into an AC output, managed by the Inverter 38 minutes ago, Solarcrazy said: I was thinking the changeover switch is a good idea incase the inverter has issues I can use the changeover to feed the geyser directly from Eskom bypassing the Inverter.. I agree, but just assure that you protect both sides of the circuit ( Origin and end-user)
