I understand, but what choice do you have if you can't remotely activate the equalizer control, and you don't want anyone to have access to the system while you're gone?
You'll have to live with equalizing them less frequently than recommended, and accept that it may diminish their life span.
Either that, or you have to change your plan, and give some competent person, access to the system.
PS: I see now that your sentence was in question form.
Are you asking me if they need to be equalized?
If so, I would think so, but the website from the manufaturer would surely answer that question in a more professional fashion, than I could.
