I am having batteries installed on the 19th Jan and my question is, is it worth going to eco7 to charge them overnight in the winter so I get next day at cheap rate until proper time of use tariffs become available?

However, there are a few factors to consider.
A. In common with other Electricity Suppliers, OVO's daytime tariff is higher per kWh if you also have E7. So there is a "break-even" point which will vary according to your annual usage.
B. We have not yet heard from OVO when they might introduce a Time-Of-Use (TOE) tariff. There is a possibility that this could occur whilst you are within the 12-month contract for E7 which you are currently contemplating.
It would useful if OVO would permit you to switch to a TOE tariff without the penalty of exit-fees. Such an announcement would surely benefit both parties and would assist customers in becoming early adopters of storage-battery technology.
Perhaps one of the Moderators,
C. There are other Energy Suppliers, such as Octopus, who already offer a pseudo-TOE Tariff, albeit not based on the inbuilt facilities of forthcoming SMETS2 meters.
D. As you haven't (yet) filled out your Forum Profile, I can't make specific comments about Smart Meters, renewable-energy input and geographical location. However, all these three subjects can influence decisions you make about battery installation.
Feel free to fill out the Profile page and then I'll be able to elaborate further.
