New install going up on Tuesday
Getting a new solar + battery install on Tuesday and wanted to get some advice from people already running SigEnergy setups.
System being installed:
* 22 x Aiko 475W panels (10.45kWp total)
* SigEnergy SigenStor EC 6.0SP inverter/controller
* 9.04kWh battery (SigenStor BAT 10.0)
* SigEnergy AC EV charger
Estimated generation around 7,500kWh/year
Roof is split across multiple orientations, so generation should be spread through the day rather than one big south-facing peak.
I already plan to ask the installers for modbus / local API access. Also plan to sign up to Axle when export approved.
Main thing I’m trying to understand is the best way to run the system initially.
I’ll still need to charge the EV overnight, so I’m interested in how people balance:
* overnight battery charging on cheap rate tariffs (on Ecotricity ev tariff)
* leaving battery capacity free for next-day solar
* EV charging schedules with the SigEnergy AC charger
* import/export settings in the SigEnergy app
* whether to use “self consumption”, TOU, or other operating modes initially
For anyone with SigEnergy kit:
* any recommended settings from day 1?
* anything you wish you’d checked before the installers left?
* any quirks with the app/software?
anything especially worth automating via Home Assistant or Modbus in the future?
I’ll also be applying for export with Ecotricity as soon as I receive the commissioning docs/MCS paperwork.
Would appreciate any advice or tips.
