Re: [RE-wrenches] Sunny Boy constant off line problem

Jeff, I suggest high AC volts is the issues. The second inverter may not have the same settings as the first. The voltage is already being pushed up by the first inverter, maybe the second one is adjusted a little tighter. The SMA config tool can show the settings. Thank you, Maverick

Re: [RE-wrenches] XW on 120v

Jay, You need to download Addendum to the Install Manual 976-0222-01-01 rev B and perform the rewriting to 120Vac and install new software using the gateway or System Configuration Tool using 120v software. Let me know if you these off list and I can send them to you. Thank you, Maverick

Re: [RE-wrenches] What inverter? (was Faulty PM-60 circuit board)

Joel, That is the fork in the road... To battery-backup or to Not Battery-backup... That is question. If you decide to battery-backup, then the SW is still sweet until it just dies. Any day now... You could switch to a Outback GVFX 3648 or XW 6048 and keep going battery-backup. If the fork

Re: [RE-wrenches] Canadian Solar blemish

I have seen this pattern twice. 1. Lightning strike near the array. But the canals are bright white or deep black. I have two of those panels for testing and they still work sorta. 2. A bad batch of EVA or an over-cooked batch of EVA during assembly perhaps. Of course, the photo does not lend

Re: [RE-wrenches] High Voltage MPPT units; Adding battery backup

Re: [RE-wrenches] What inverter? (was Faulty PM-60 circuit board)

I agree that one SMA costs less than 24 M190s, but I get two main advantages, 1. individual monitoring of these old modules. (ok, two in string). Any module that can fire up the inverter will report to the enlighten website. 2. Simple expansion of the system. 24 inverters will already be at

Re: [RE-wrenches] Convert Grid Tie SW4048 to Backup System; Add New Inverter, AC Coupled

Dick, What are the customers goals? Battery backup works, but requires knowledge of the customer's expectations (energy, power and flexibility). What is the budget for the upgrades. Do they want more solar? They don't want battery maintenance, will they want generator maintenance? Ask these

Re: [RE-wrenches] High-power MPPT/Charge Controllers?

Wow! The most I have in one Outback install is 8 MX60s and 8 VFX3648s. Overall the customer has been happy with the performance and the stacking power save feature helps with idle power draw. As for the OPs request, the most PV still remains to be about 5000 watts gross power per controller

I agree. There is one Group X panel. The 72 cell mono. 24v nominal, 62.2 x 31.8 with varying frame thickness. I use them for all grid interactive and off grid systems. They are more ergonomic and higher voltage helps as well. Conergy, Mage, suntech, astroenrgy, sharp, and many other make or

Re: [RE-wrenches] Xantrex 600v charge controller

We used a big ol' fat square D HU361RB for the disco. Too bad Xantrex did not have the forethought to build a SMA type fused segmenting disco. I even thought about building one or buying the SMA type. So budget that extra expense. Unfortunately, Xantrex also reserved the bottom of the chassis

Re: [RE-wrenches] Small battery bank vs too large array

I say it is waste of time. 1. AGM batteries can take the high current and you are right, the absorb voltage is reached and the absorb current is tapered rather quickly. Current generation charge controllers are rather fast at the transitions. I have a bunch of data from a system with a
