[RE-wrenches] Hawker versusu MK
Friends: We are shopping for industrial, flooded, lead acid batteries. We are considering 12 volt packages in the 1800 AH range. Under consideration are: Hawker 12-25W-23S at 1705 AH or MK 106M1033STB at 1896 AH. Have any of you had experience with either, or recommend another option? As always, I am extremely grateful to all of you for the limitless wisdom offered.

I install large battery banks ALL the time. We DO NOT use any battery that is incased in a metal enclosure. REAL pain to move, cells DO go bad when they do its a real pain to bring the engine hoist to remove them. Hard to keep the cases from leaking rusting. We DO use the Surrette 2 volt cells in the dual container exclusively. These are rated as a containment vessel, much easier to move. In the event when a cell does go bad, use a jumper to bypass the bad cell, operate w/ a lower LBCO setting leave the CC settings the same, while waiting for replacement. 1700 AH -2400 AH. By the time you have the tractor/back hoe on site, my 2 volt cells are up n running! E mail me off list and I can give you a few tricks to move them.

[RE-wrenches] Hawker versusu MK
Here's a third for 2V Surrette's... However you should discuss details with this list or someone at Surrette regarding your application. For an example, Solar Power source? C/rate? Are you replacing a set of golf cart batts or batteries with similar charging needs as these large cells? The 2V 1766AH cells seem to prefer being charged longer and slower than say a T-105 or an L-16 to ensure proper SG's (others please chime in hear with similar/different experiences). Yes, being easier to move is great...a handtruck or 2 bodies works perfect. Dual container simplifies your battery box AND keeping the tops clean. The large/tall area above the plates means less watering. One warning though is insist on getting all the cells from one batch. If your supplier has to wait for cells from some other distributor to make up your pack, ask to wait for all cells to come from one production batch. I know a lot of folks have and love metal cased 12V packs (I'm still working one myself) but I won't be going that route again for a variety of reasons. It's a big investment, do your homework. there's 2 more cents worth.

Re: [RE-wrenches] Hawker versusu MK
William.we have used a set of industrial flooded lead acid batteries made by a company called Storage Battery Systems (www.sbs*battery*.com)The batteries are 2V batteries with 3200Ah capacityThey come with a variety of warranty options. Our client decided on the 20 year option (5 years full, 15years prorated) They have a clear case so you can easily with just a glance see the level of the electrolyte.They have tubular plates and came with all the interconnects which cover any exposed metal at the terminals once they are hooked up.. except a small hole to insert your voltmeter leadsThey have 4 terminals on each battery so if you need to run multiple homerun cables you have plenty of plenty of options with out having to double lug your battery cables on a single terminal. They have been in operation for almost 4years now without so much as showing any hint of wear.While they are expensive they also offer extras such as seismic racking, spill containment systems, and hydrogen gas level alarms. The feeling that i got from this company is that they are more in the industrial battery market and not so much the renewable energy marketThey are worth a look.we are really happy with their product More frequently though we use the Rolls Surrette series 5000 batteries...They also have been reliablewe once had a reverse polarity from the factory so check polarity of each battery before hooking them up.These are our main go to batteries when a larger than 800ish Ah battery bank is called for. Trojan also has their newer line of industrial batteriesWe have used them a couple timeswarranty is not as good as the Rollsbut they have the dual cases like the rolls and seemed like good batteriesBoth the Trojan and Rolls are supplied with string interconnects(make sure to remind your distributor) We have had to train our distributor to supply good quality stainless bolts (with sufficient length) with lock washers and washers with all battery purchases Good luck...

Re: [RE-wrenches] Hawker versusu MK
I've got two Hawker installs out here, a 48 Volt and a 24 Volt system. Both are going on 6 years or so. Clients are happy, I'm happy. It does resemble work to move and place them. We typically use Egyptian techniques when heavy equipment isn't available or appropriate. Inclined plane, big pry bars, rollers, come along, block tackle. It's kind of fun to try to outsmart the mass. It's interesting to experience gravity's effect on lead, atomic weight 207.2. Glad it's not Uranium at 238. Thankfully, we've not had to replace a cell. That always sucks, regardless. If I remember correctly, the steel cans had welded seams. The cans make the use of insulated tools even more important. Should you ground the cans??? Speaking of replacing cells. I looked at a 5 year old bank of 8 Rolls L16s this weekend. Two of the batteries had a dead cell. This in a bank that had a single battery replaced at 6 months or less because of a bad cell. I've also got a 7 year old bank of 12 Surrette / Rolls 2 Volt units installed. The only problem so far was on day one when they arrived. They were shipped on a single, narrow, beat up pallet. Some had obviously tipped over in transit and had lost a considerable amount of electrolyte. Northern Arizona Wind Sun user's forum has posts reporting similar experiences. I dread receiving expensive pallets of batteries and modules from shippers. High percentage of damage. Steel cans instead of plastic wrap is worth thinking about. Hope this doesn't just muddy the water.

[RE-wrenches] Question re Midnite surge arrestors
Wrenches, Very seldom do inverters in off grid systems ever go to sleep anymore, given the increase in phantom electronic loads and greater customer expectations. Coupled with lower module prices, we usually size larger arrays and inverters remain on continuously. However, we also service and upgrade many existing systems, and some customers still want their inverters to go into search mode. They typically either have gotten used to a more energy frugal lifestyle over many years, or (to their credit) choose to buck the system and live with a lighter energy and resource footprint. Twice in recent months we have added Midnite MNSPD MV surge arrestors to the AC output of smaller systems and discovered that the inverters will no longer go into search mode. It doesn't appear to make any difference where the search watts threshhold is set. One system used a 24V Outback FX2524T (with current boards following a nearby lightning strike) and the other used a Magnum MS2812. In the former case, we defeated the search (against the customer's preference, as she liked the total silence once her day was done). In the latter, the customer rejected and we removed the surge arrestor once it became clear that the inverter wouldn't sleep. Has anyone else experienced this? Is there a fix for it?

Re: [RE-wrenches] Question re Midnite surge arrestors
Ryan, I may have found the answer to my original post, but it raises more questions. I wrote that these were MV units (MNSPD300), but I checked with my lead tech and learned that in both cases he used LV units (MNSPD115). Could this be the reason? He told me that he has used the LV with 120V inverters and the MV with 120/240V inverters. The instruction manual states that the LV units are designed to be used on nominal 90VAC and 115VDC circuits, and have a Maximum Continuous Operating Voltage of 180V. The manual states: "The MidNite Solar SPD voltage rating should be chosen according to the nominal voltage of the system. Do not install an SPD with Maximum Continuous Operating Voltage (MCOV) below the nominal voltage of the system; this will deteriorate the SPD and making it unavailable when you most need it." If this is true, then the LV (with its 180 MCOV) should be fine at 120VAC. The instructions are confusing: should we use an MNSPD115 or an MNSPD300 with 120VAC output? And in this case, could this be the cause of the failure-to-sleep problem? If we should be using the MNSPD300 with 120VAC inverter output, then the description on the Midnite website is confusing at best. It states that the MNSPD115 "is designed for both AC and DC systems and provides protection to service panels, load centers or where the SPD is directly connected to the electronic device requiring protection." But service panels and load centers seldom if ever carry AC at less than 90VAC, the nominal rating of the MNSPD115. Please clarify all of this!

Re: [RE-wrenches] Hawker versusu MK
Hi Dick, Best trick I ever learned for these metal cased is to build a wheeled base with steel wheels. Yea, still have to get them onto the base, but then its easy. Also when I use metal cased batteries I like to have them with removable series interconnects not the welded type. Interesting to hear the comments on the Rolls shipping. I've seen that problem myself, but didn't realize that it was so common. jay peltz power On Aug 13, 2013, at 9:31 AM, Richard L Ratico wrote: I've got two Hawker installs out here, a 48 Volt and a 24 Volt system.

Hope this doesn't just muddy the water.
