  • Looking for a Clamp-on DC (and AC) meter

    Don't need a high end one, as it will be used at home on an occasional basis, not daily on my job. But would like one which is easy to use and will last. Primary use of the clamp on will be measuring current (and V too if that's possible) on panel leads and the like. Thought that folks here...
  • Lightning Protection

    So I am revisiting the lightning/surge protection on my two ground mounts, hoping to upgrade it. Fairly typical setup, two identical ground pole mount arrays, electrically tied together in parallel for the DC output. The panels and frame have a 6ga solid copper ground conductors which go to...
  • Looking for System Upgrade Suggestions

    I have been "kicking around" some ideas on upgrading/expanding my system for a while now. I have a few possible solutions/directions I've thought of, but wanted to run it by folks here to get feedback and/or new ideas. First here is my current system: 2600W of PV panels on two ground mounts...
  • EG4 18Kpv Dump Load

    Been looking at possible replacement inverters, and the EG4 18Kpv seems like a pretty good match for my needs. One "feature" which I had hoped to implement in my system was adding a dump load (hot water heater element) to make use of extra power when the batts are close to fully charged. From...
  • Tiny Solar Project

    I have been kicking around ideas for a tiny (maybe even a nit) solar project, and was looking for ideas/suggestions. We have a chicken coop on the property, and I put in an automatic door opener, which has been working fine. It runs off of a 6v lantern style battery which typically lasts just...
  • Looking for a small MPPT SCC

    I have a solar well pump (DC) setup, been using it for 6+ years now. It has its own pump controller with a built in charge controller (PWM). It generally works well, but my 2 PV panels can't quite keep up with water needs in the summer. Temporarily I augmented the PVs with a 24v battery charger...
  • Battery Advise for Grid-Tied System

    I have an older (circa 2000) grid tied system using PVs, a Trace SW4024, and ~20KWHs of AGM batteries. The batteries are beginning to show their age and so I have begun investigating which batteries would be a good replacement for them. This system will be attached to a working grid almost all...
  • Using CT's in an Unusual Design

    I am planning my AE upgrade and starting to get the permits/approvals. It will basically be a major replacement of the current 20+ y.o. system with a new inverter, more PVs and new battery. Fairly straight forward, but there is one thing which has been troubling me. The placement of the CT's...
  • Pb-C AGM Batt questions

    So I am curious to get some ideas/direction on the care and feeding (aka charging and use) of lead-carbon batteries. They seem to be a fairly new design, with what would appear to be some real advantages for stationary uses (high current charging and draw, high cycle counts, much cheaper than...
  • Altitude rating on Inverters

    Just curious about the max altitude rating on inverters. I am at 8000'+ elevation (about 2500m), and it seems several of the popular AIO inverters are rated up to 2000m, a few for 3000m. The only thing which it seems might be effected by altitude is cooling efficiency with the thinner air, which...
  • Waterproof DC Connector

    I am looking for a water and weather proof DC connector to allow me to plug in a battery charger to an outdoor DC-Solar well pump system. Something which can handle 10A or so. And would be nice to have the + and - connections all in one polarized connector. This connector would hang off the pump...
  • Looking for solid intercell bar type connectors

    Ideally in tinned copper. I have some flexibility as to size, but roughly 3.5" to 4" OC hole to hole. Equivalent to 2/0 wire or better. There does not seem to be much out there for sale, and the one place I found seems to only sell to industrial accounts. Does anyone know of a place to buy these?
