[RE-wrenches] Two Dilemmas

Fri Jul 24 07:13:39 EDT 2020

Use rope or I have nylon straps w/ snaps that I use, if the cells are bolted, otherwise sawzall the interconnects and a rope thru the bolt holes, n lift. There are times that I will hit the case w/ a large hammer to start the removal of individual cells. When installing new cells silicone spray or dish soap will ease installation.

>> Northwest Energy Storage (www.solarone com, I think) supplies a short, heavy nylon strap with clevises at each end for raising and lowering each cell. You might contact them to purchase one. 
>> At one remote site, the client suggested that I buy a cheap engine hoist from Harbor Freight, as it would be cheaper than renting a professional one.

>> 2) the older Trace SW series is early technology in regards to its sell efficiency,  because of the lack of what was dubbed ‘silent sell’. The general number from when it was about the only game in town was about 55%. I would suggest upgrading to a modern unit if it’s primarily used for selling back.

After reprogramming the CCs and inverter with new charging parameters, I can’t get the Trace to export excess production once the batteries are charged. I do have the inverter set to “Sell” mode What am I missing? I have had little experience with the Trace line.
