Avoid. poor software makes this good product almost useless for days at a time
We had SPH inverter and 10kwh batteries installed jan2023. chose this simply because these were the only product available end of 2022 but this was a mistake- should have waited for better product to arrive in stock. On the good side, the system produces power and generally charges/discharges battery appropriately. But the app and desktop monitoring is worse than useless- there are many periods of 3-5hours when it cannot update. then it guesses what happened between updates so that's highly inaccurate. If you haven't had solar/batteries you might not imagine how serious a problem this is: you can't see how much solar there is, how full the battery is or how much has been imported from the grid. Then there is the inability to program the batteries to charge overnight (on cheap electricity) unless the app is working. Together these issues cover about half of the usefulness of having solar and batteries, so the poor software definitely means that this product is not at all recommended after 4 frustrating months. Avoid.
