Damaging a mini-split heat pump has happened from this at a home in Florida. Hard always to prove as anything connected to the grid can be surge damaged also. Fujitsu did pay the warranty repair but would not if it happened again. In cases where I have been approached to AC couple, I just recommen

Hi Mac Thanks for mentioning this, I’ve wondered about it a lot. Maybe someone who’s a motor or electronics expert can chime in about what potential damage can occur. Electronics, motors, VFD’s, are used to seeing voltage +/- by a fair amount, but frequency is rarely off by more than a fractio

The solar self consumption mode is a requirement in order to qualify for the SGIP incentive for PV-paired systems. For residential systems, the storage system must discharge a minimum of 52 full cycles per year which equates to once per week on average. In addition, solar self consumption mode can

Yes, PG&E. The Self Generation Incentive Program (SGIP) created a flood of applications and PG&E is having a hard time keeping up. Hopefully it will get easier. We are enabling self-consumption and backup modes. The Powerwall charges daily from the solar and then discharges to a owner-set minimum

An installer I have been working with here in southern VT has also repeatedly applied to become an installer with Tesla for powerwalls with no response.I cannot in good conscience recommend their products based on their history and unresponsiveness in our area. They may be great for Puerto Rico,

Hi Dave - I keep hearing that Tesla is having a hard time keeping up with demand, so they may not be very motivated to add more dealers at this point. Just speculation. Yes, the max continuous and peak powers add as you add up as you add more powerwalls. Energy capacity adds too. Yes, Powerwall h

Marco, Thanks for sharing, it is good to hear details from an installer who is living with a Powerwall. We starting selling the Powerwall 2 in 2017 and have worked up a large pipeline. We have about 20 installed so far, but are still waiting on utility permission to operate which is taking a long

Tesla also promises an offgrid version soon that will be DC coupled. The price is not bad for 13 KWH right now. The system is 50 vdc which to me is usable as it stands. All of the 400vdc batteries are not conceived right in my humble opinion! Not to mention for safety in my home! Dave Angelini Of
