Ditto here too.
98% of my clients use the HUP and its bomber I have a client that is over 20+ years at this point. With regular EQ as required by SG readings, Battery bar maintenance, watering, & testing they just keep going. I have a 14 year old set I pulled out of a clients house during an upgrade to a much larger system and they are doing exceedingly well in float mode in grid tie. I EQ once a year for grins but SG readings have not indicated it was required. Sets I installed in Washington 21+ years ago are doing well from reports there too. If you look at the specs on 50%DOD & 80% DOD I have not seen any other manu with a comparable spec. www.hupsolarone.com check it out. I went to larger batteries 26 years ago & HUP when NWES made them available. Less cells to water, less connections to address issues with, less cables to crimp & protect from acid, & almost 0 battery bank change out once in to HUP. I have replaced a few large Rolls with HUPs & problems went away. The down side is handling. I now own a 3 ton - single axel trailer with an overhead I-beam that extends off the back with jacks on the rear to stabilize and a 1.5 ton set of chain falls to deliver & set. Once it hits the ground we use a safe mover (rated at 1985# each) to roll into place. The cells do come out but jeez what a back ache. What will I install when I go off grid here in the next year? That's still to be determined but its either going to be HUP or possibly Aquion... Just not sure the price difference will be worth it. I know the HUP as an installer and a home owner and I have total faith in them as the best FLA battery currently available. ---------------------------------------------------------------------------- Dana Orzel Great Solar Works, Inc - NABCEP # 051112-136 E - d...@solarwork.com - Web - solarwork.com O - 970.626.5253 C - 208.721.7003 "Responsible Technologies for Responsible People since 1988" P Please consider the environment before printing this email.

Get away from all L16s. Go to one string of industrial cells. There are numerous well-respected brands. I would put HUPs at about the top. www.hupsolarone.com. Spend some time on this website and it will become more clear.

One client is considering spending $12,000 on a nickel - iron battery bank he found on the web. This seems like a ridiculously large investment, but he is feeling desperate. We urgently need another option from the Trojan L-16s. How are the Surrette L-16s holding up? Would you recommend them as worth the extra investment? What is the best battery to use in an off grid system these days.
