In wondering about how I might send all or part of my 4000 watts worth of Solar Panels current to a water heating task; ... when my 24v LiFePO4 battery bank is just under fully charged (near cut off set for top voltage:
... I just ordered one of these to play with later:
I will most likely use this later connected this up to my (overkill 500 amp rated / $40 used) KILOVAC EV200 Series Contactors to disconnect part of my Solar from battery charging task / and at same time switch a good portion of my Solar Array current to Water Heating (maybe for heating my smallish spa/ & then have to consider other option if that tops up nicely without using my natural gas heater). I will soon have 4000 watts of solar panels up and dial in, and might later add an additional 2000 watts (as I have third LV2424 on wall for that easy option). I may switch 2/3 of my PV current at 6 panel Solar Arrays ... or at full Solar Array Current junction IN to each of my LV2424 All In Ones. ... just in brainstorming phase at present.
One person on Amazon with same ideas asked: Want to turn on water heater element once battery bank reaches float voltage and turn element off when voltage drops below X. Can do? ... got a few answers including: Depends on what your "float voltage" is. There are 3 versions of this relay dependant upon voltage monitoring range 12v/24v/48v. I'm thinking you may be looking for a current monitoring relay so when your charger output drops to maintain current vs charge?
So, ... I will also look at current monitoring options (did not find any yet), but think this voltage monitor relay switch may be perfect for my needs at a very ok price.
Wow: Ideas for my creativity basket; with equipment options I can get delivered to my door in California by just pushing buttons on my pc laptop (with a credit card. :+)
