Huawei FusionSolar app disabling solar charging

tallac

I have a Huawei home storager battery and use the FusionSolar app (on Android) to manage and monitor things.

I've also got the engineering access code for logging into all the more advanced settings as well.

Does anyone know how I can prevent my solar array from charging up the battery? I wish any surplus solar to be exported to the grid instead.

Thanks in advance

From the front page, select devices at the bottom of the page. On the next page select Connected devices. On the next page, select battery. On the next page, at the top right are 4 dots. Selecting them brings up Parameter settings and Modify device name. Select Parameter settings. Select Working mode. At the bottom of the next page select Priority of excess PV energy. You want Fed-to-grid preference.

You kind sir are a legend. Thank you!!

On a related note. If I wanted the house to pull from the battery before using the solar generation, where is this setting in the app?

Is that even possible? Where would the solar go?

It should be. Basically, I want solar generation to always go to the grid.

Why? Because on my Octopus energy tariff, I pay 7.5p per unit at off peak and I get 15p per unit to export to the grid. Given I have both solar and a home storage battery, I may as well charge my battery to 100% in off peak which will see me through the entire day and then export all solar generation to the grid.

I can easily manage with just 50 to 70% of battery charge per day so should be doable.

Are you sure of your cheap rate electricity import charge? It might get that low on a flexible tariff but flux only just balances  cheap import and standard export by the time inverter losses are allowed for. Might be better saving the energy in the battery to export at peak rate just leaving enough to take the house to cheap import rate during the night.

I'm with Octopus Energy on their Intelligent tariff. 7.5p off peak import and 15p for any time export.
