Re: [RE-wrenches] Generator choice for Sunny Island

I have had generally a good experience with Sunny Island battery charging. There are definitely way too many parameters to set, but their charging algorithm is designed to bring batteries up to ~90% on the "boost" charge (every 1-2 days), 95% on their "full" charge (typically every 10-14 days) and

Re: [RE-wrenches] Generator choice for Sunny Island

My experience with Sunny Islands are that their SOC can be off by quite a bit. Unfortunately with sealed batteries, you can't check SG with a hydrometer to confirm, and tweak the settings. Probably the best you could do, is shut the system down and let the batteries sit for long enough to take

Re: [RE-wrenches] Generator choice for Sunny Island

Hi Drake, Good questions. Yes, the taper charge appears to be working well. I've been to the site a couple of times where loads were low, irradiance was high, and battery SOC was ~90% and the Sunny Boy was just covering the load and a little trickle charge. I have noticed that the SOC seems to ma

Re: [RE-wrenches] Generator choice for Sunny Island

Are you getting a good taper charge with this system? Are the batteries reaching a decent state of charge from the AC coupled connection with the inverter? Thanks, Drake At 11:08 AM 7/23/2017, you wrote: August, Of course the genny itself has its own emission of noise but the
