Perhaps this will help to understand the rules:
In[1]:= sols={{{V->26.5173},{V->340.686},{V->191821.}},{{V->26.6798},{V->326.358},{V->135843.}},{{V->26.8489},{V->312.824},{V->98061.}},{{V->27.0252},{V->300.031},{V->72039.1}},{{V->27.209},{V->287.932},{V->53792.5}},{{V->27.4009},{V->276.484},{V->40774.4}},{{V->27.6013},{V->265.647},{V->31339.2}},{{V->27.8109},{V->255.384},{V->24398.6}},{{V->28.0302},{V->245.661},{V->19221.5}},{{V->28.26},{V->236.446},{V->15312.4}},{{V->28.501},{V->227.71},{V->12322. 2}},{{V->28.754},{V->219.424},{V->10009.8}}};
In[2]:= lst=Flatten[sols]
Out[2]= {V->26.5173,V->340.686,V->191821.,V->26.6798,V->326.358,V->135843.,V->26.8489,V->312.824,V->98061.,V->27.0252,V->300.031,V->72039.1,V->27.209,V->287.932,V->53792.5,V->27.4009,V->276.484,V->40774.4,V->27.6013,V->265.647,V->31339.2,V->27.8109,V->255.384,V->24398.6,V->28.0302,V->245.661,V->19221.5,V->28.26,V->236.446,V->15312.4,V->28.501,V->227.71,V->12322.2,V->28.754,V->219.424,V->10009.8}
In[3]:= Partition[Table[lst[[j,2]],{j,1,Length[lst]}],3]
Out[3]= {{26.5173,340.686,191821.},{26.6798,326.358,135843.},{26.8489,312.824,98061.},{27.0252,300.031,72039.1},{27.209,287.932,53792.5},{27.4009,276.484,40774.4},{27.6013,265.647,31339.2},{27.8109,255.384,24398.6},{28.0302,245.661,19221.5},{28.26,236.446,15312.4},{28.501,227.71,12322.2},{28.754,219.424,10009.8}}
These are the solutions triplets.
