Offgrid Cabineer, N.E. Ontario, Canada
NOTICE: UPDATING November 2022 WIP
Good Day everyone,
Overview: There is no grid here, no phone lines, cell is so-so (to be polite) so satellite internet is here (not bad actually). I do not have 240VAC, this is a 120V system only. My Solar Panels are mounted separately from my Powerhouse which is 40' (by buried wire) andis independently heated and also highly insulated. The cabin is another 75' (by buried wire ;-) ) from the Powerhouse.
If you want to know more about my cabin, See Post #2
Panel Mounting: fixed ground mount @ 45 degrees.
8X Canadian Solar CS260P in 4S-2P configuration.
Logical Diagram: (Version 5 updated Nov. 2022)
NOTE: Spring 2023, System will receive another Upgrade. This will add a Midnite Classic 150 SCC (in parallel with the 200 as Master) and supplied by 6 QCell 395W Panels in 2S3P configuration, adding an additional 94A Charging Capacity.
Components in Logical Drawing: products links are blue)
Midnite Solar Classic 200 MPPT Solar Controler Midnite Solar Controllers
Midnite Solar E-Panel with 250A Main Breaker and other breakers. Midnite E-Panels
Samlex EVO-4024 Pure Sine Inverter/Charger Samlex EVO-4024
Blue Sea 9001E, 1,2, 1&2 DC Switch for the "split" battery bank. BlueSea E-Series
KUERL 30V-12V Step Down Transformer kuerl LINK (30V to be able to handle Charge Voltage !)
Pike Industries 400 Amp Solid Copper Busbar 4 Stud (5/16" Zinc Plated) Common Bus, Terminal Block.
Peacefair PZEM-011 AC Digital Meter. Amazon.com link
Champion 4650W Inverter Generator (Gas Only, Manual Start model)
The (-) post shown and ALL Battery Pack Terminals have BlueSea Insulators - Stud Cable Caps
Each Battery is FUSED at the (+) BusBars with 200A MRBF fuses (Made by Bussman) sold by BlueSea
Battery bank info: 1293AH / 33.101 kWh
1x 24V/105AH LFP Battery Assembly (EVE, Grade-A) from Luyuan Tech * This is a Utility pack, temporarily in the Bank.
2x 24V/175AH LFP Battery Assemblies (aoyoupower cells recovered from a Bodged Pre-assembled pack. SHUNBIN DISASTER)
1x 24V/280AH LFP Battery Assembly (EVE, "B" 280AH cells from XUBA.) NOT recommended Vendor
2x 24V/280AH LFP Battery Assembly (EVE, 280-2 Pack "B" & 280-3 Pack "A" Matched & Batched 280AH cells) Luyuan Tech
Each LFP Pack is equipped with;
- JiKong BMS model # B2A24S15P with Switch, no LCD Screen. Link to product @ Luyuan
-- 2A Active Balancing, supports 8S-24S, Bluetooth & RS485.
Due to my equipment & configuration, there are 2 External AC Breakers serving the Inverter (per inverter docs) :
1, Square-D QO140 40A on the L5:30 line from the generator to Inverter *Charging at 75A draws 22A+/-1A/2500W+/-100W actual.
1, Square-D QO145 45A between the Inverter to the 120VAC Powerhouse Base Panel .
A Close look at the Logical Diagram will show the different components and information related to it.
NOTE: I only use DC Breakers, all breakers supplied from Midnite Solar Inc. which are manufactured by Carling Technologies USA. They are simply the BEST there is and the prices reflect that. Of course when it comes to safety & security, compromises should not be a part of your equation.
Cheapest I could find are here:
Main Breakers in the E-Panel below. I used 175A with 3KW Inverter/Charger. 250A when upgraded to Samlex 4KW Inverter/Charger
