Revised on 1 October 2026: The maker page prints only the cable lengths (a 20 ft shielded wire and a 3 ft power wire) and says nothing about communications, so no communications claim can be recorded.

Retrieved Sep 21, 2026
Redodo’s Product Warranty Policy, revision V4.0-RPWP-260430, a three-page PDF served from Redodo’s Shopify CDN, linked as "Warranty Policy" from the footer of every page and from the Product Manuals index, and captured byte for byte on September 22, 2026. It establishes the published terms on the access date: the warranty runs from the original buyer’s date of purchase and the order number is the proof; a Warranty Period table gives five years for brand-new 12V, 24V and 36V batteries of 20 Ah and above, all 48V batteries and 51.2V batteries of 30 Ah and above, three years for the 12V 6/10/12 Ah packs, two years for AC-DC and DC-DC chargers, three years for controllers and MPPTs, two years for the 12V 1000W, 2000W and 3000W inverters, one year for the 12V 300W inverter, the 40A socket, the portable battery box and the 500A battery monitor, two years for the ANL fuse, and shorter terms for Like-new stock; Redodo repairs at its own expense, replaces an unrepairable product with the same or an equivalent model that may be refurbished, and adds a 30-day repair warranty on top of whichever term is later. It also sets a 30-day return window, a full refund within twelve months of delivery and a pro-rated refund after that (purchase price divided by total warranty months), and lists the exclusions. It names no individual SKU, carries no signature or issuer record, and establishes no claim outcome: it is Redodo’s own published policy text, not a contract executed with a buyer.

Retrieved Sep 21, 2026
Manufacturer-operated Shopify product page for the Redodo 500A Battery Monitor with Shunt (SKU R-MONITOR500A-B1), captured byte for byte on September 22, 2026 during a crawl of every product Redodo lists at www.redodopower.com/collections/all/products.json. It establishes what Redodo published on the access date: the product title, the variant list with its ordering SKUs, prices and stock flags, the feature bullets, the SPECS table (its OTHERS, BASIC and DIMENSIONS sections), the FAQ block and the images the page presents. It does not establish more than that: Redodo publishes no datasheet for any product, the SPECS table carries no revision number, issue date or test standard, and every figure on it is a marketing-page value rather than a signed specification. Redodo publishes no manual and no datasheet for the monitor; its Product Manuals index lists battery manuals only. Standards named in the Certifications row are manufacturer claims that no issuer record was read against.

Warranty

Remedy: Repair at Redodo’s expense; a free same-or-equivalent replacement where the product is unrepairable, possibly refurbished, plus a 30-day repair warranty and the longer of that or the remaining original term. A buyer who insists on a refund for special reasons is refunded in full within twelve months of delivery and pro rata after that, the monthly deduction being the purchase price divided by the total warranty months
Official warranty
Sources
Summarised from "Redodo will repair, at Redodo’s expense, any Redodo product that fails to operate during the applicable warranty period due to a defect in workmanship or material", "A 30-day repair/replacement warranty is provided from the date the repaired/replaced product is received" and the depreciation formula "Monthly Deduction = Purchase Price ÷ Total Warranty Months" in revision V4.0-RPWP-260430. The policy does not say who pays shipping on a warranty repair, only on a 30-day return.

Fell in love with the simplicity of the first one on 85 year old mother in law's offgrid home.

Software: 5/5
Reliability: 5/5
Build quality: 5/5
Ease of install: 5/5

85 year old mil was having difficulties understanding 30 year old trimetric monitor. She loves the complete simplicity of this interface. Have since installed 5 more for myself (35 years off grid) and a few friends that needed the simplicity. Easy to use and understand, all necessary info on one screen. Can tell capacity from across the room. Prices from $45 to $65 2024 to 2026.
